NodeXL Teaching Resources

A number of instructors have been using NodeXL to help teach social network analysis. It is relatively easy to use compared to many other network analysis and visualization tools, while still providing a rich set of metrics and visualization features. It is also free and integrates with the already familiar Excel 2007 or 2010. This page is meant to collect information that can be useful in teaching with NodeXL. Please email Derek Hansen (shakmatt@gmail.com) if you have been using NodeXL in your teaching or have resources that may be helpful to other instructors.

Derek Hansen, Ben Shneiderman, and Marc Smith have written a book titled Analyzing Social Media Networks with NodeXL: Insights from a Connected World published by Morgan Kaufmann. The book includes 3 parts: Part 1 introduces social media and network analysis, Part 2 is a tutorial introducing core network concepts while walking through the major features of NodeXL, and Part 3 is a collection of case studies written by various network experts analyzing different social media tools (e.g., email, forums, Facebook, Twitter, YouTube, Flickr, wikis, and hyperlink networks). If you are planning on using the book in any classes please send me a note indicating the class you'll be using it in and I'll add you to the list below. The datasets used in the book are included below.

Slides from Analyzing Social Media Networks with NodeXL: Insights from a Connected World that include all images and their descriptions are below:

NodeXL Sample Files (version 1.0.1.219 or later, for 32-bit or 64-bit machines)

IMPORTANT NOTE: After downloading these files make sure and use the Import --> "From NodeXL Workbook Created On Another Computer" to open the files. This will create your own copy and make sure that these versions open well in the most recent version of NodeXL that you have hopefully downloaded. Make sure you are using version 1.0.1.219 or later.

Kite Network dataset - the simple kite networks used to teach basic network metrics
Serious Eats dataset - a multimodal network connecting people to blogs and/or forums
US Senate 2007 dataset - the co-voting network of US Senators in 2007
Les Miserable co-appearance network - the network of characters in Victor Hugo's book based on their appearing in the same scenes together.
css-d_email list network - a network of those posting to the css-d email list in Jan and Feb of 2007 (email addresses are anonymized)
ABC-D_email list network - Discussion list network discussed in Chapter 9 of the book. Note that Eigenvector centrality is calculated slightly differently, as is Betweeness Centrality (which used to be normalized to the node with the highest score, but no longer is).
Ravelry_Raw - Raw bimodal dataset of Ravelry users connected to 3 different discussion forum groups (discussed in Chapter 9 of book).
Ravelry Completed - Ravelry dataset and completed visualization that matches Figure 9.10 in book.
The following Enron Datasets are based on a subset of all available Enron email messages coded by researchers at the University of California at Berkeley (see
http://bailando.sims.berkeley.edu/enron_email.html). Slight variations in numbers of email messages may result from different ways of handling non-standard email messages.
Enron_Dataset_Unfiltered - includes all 1,801 edges derived from work-related messages occurring later in the collection that discuss the California Energy Crisis.
Enron_Dataset_FERC_only - includes subset of unfiltered dataset that includes the term FERC somewhere in the email message (this is the one analyzed in Chapter 8 of the book).
Enron raw messages - Raw Enron messages that can be imported into NodeXL as described in Chapter 8 of the book)

A very large and growing collection of images and NodeXL files are uploaded to the NodeXL Graph Gallery. Click on the image you like and look for the Download as NodeXL file link at the bottom of the page. Many of these graphs show off NodeXL's latest features which are not covered in the book.

Assignments based on NodeXL

Feel free to use and/or modify the assignments provided below with proper attribution. If you have your own assignments to share please send them to Derek Hansen at shakmatt@gmail.com

Facebook assignment for beginners. (see IT 101_Facebook_Lab.docx). This assignment was created by Derek Hansen for BYU's IT 101 students who have never been exposed to network analysis before. Students can complete it with some training in approximately 1-3 hours.
Advanced visualization, analysis, and interpretation assignment. (see Social Network Analysis Homework Assignment.docx). This assignment was created by Derek Hansen for BYU's IT 515R: Web and Social Media Analytics course. Students work on this for several weeks. Ideally they will first get feedback from peers and the instructor on the goals of their analysis and the data they'll be using. Next they create a draft visualization that is shared with their classmates and the instructor for feedback. Finally, they present the results to the class and post them to the NodeXL Graph Gallery (after anonymizing data if it is private).

Complete NodeXL Release History

1.0.1.243 (2013-05-19, private release)

The Twitter Search Network now uses experimental shared term thresholds. This is part of an effort to obtain meaningful edges without running into Twitter's new rate limits.

1.0.1.242 (2013-05-01, private release)

The shared word user threshold can now be specified in the network configuration file used by the Network Server program. (For advanced users of private releases only.)
Bug fix: If you specified shared hashtag, URL, word, or word pair edge relationships in the Import from Twitter Search Network dialog box, the graph summary (NodeXL, Graph, Summary) did not mention the fact that the graph included those edges. (Private releases only.)

1.0.1.241 (2013-04-25, private release)

Bug fix: If you imported a Twitter network that included the empty hyperlink "http://" somewhere in the network's text, Excel would refuse to save the workbook. The error message started with "Errors were detected while saving..." This is an Excel bug that will also arise if you type "http://" directly into a cell. This change does not fix the latter problem.

1.0.1.240 (2013-04-24, private release)

If you check "add statistic columns to the Vertices worksheet" in the Import from Twitter Search Network dialog box, no additional time will be required to get the network. This used to require additional Twitter requests, and it was marked as "slower" in the dialog box.

1.0.1.239 (2013-04-08, private release)

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

1.0.1.237 (2013-03-25, private release)

Same as 1.0.1.236, but with additional edge options.

1.0.1.236 (2013-03-25)

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.
If you set the Visibility of vertex X to "Skip" and vertex X has adjacent vertices that are connected only to vertex X, then those adjacent vertices are now skipped as well. Previously, the adjacent vertices would remain in the graph as isolates.

1.0.1.234 (2013-01-25, private release)

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.

NodeXL is a free, open-source template for Microsoft® Excel® 2007 and 2010 that makes it easy to explore network graphs. With NodeXL, you can enter a network edge list in a worksheet, click a button and see your graph, all in the familiar environment of the Excel window.

Visit the NodeXL Graph Gallery to see the wide variety of graphs that have been created by the NodeXL community.

What's New

The latest version of NodeXL introduces grouping by motif simplification, which is a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships.

NodeXL can group the graph's vertices using three kinds of motifs. Using fan motifs helps get rid of the large fans of singly-connected vertices around the edge of your graph. Connector motifs, instead, focus on redundant connections between a pair of anchor vertices. Finally, cliques allow you to simplify completely connected groups of vertices.

To use this new feature, go to NodeXL, Analysis, Groups, By Motif in the ribbon.

This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland. For more information about their work, please see HCIL-2012-29.

See the Complete NodeXL Release History for details on additional changes in this release.

NodeXL Features

Flexible Import and Export Import and export graphs in GraphML, Pajek, UCINet, and matrix formats.
Direct Connections to Social Networks Import social networks directly from Twitter, YouTube, Flickr and email, or use one of several available plug-ins to get networks from Facebook, Exchange and WWW hyperlinks.
Zoom and Scale Zoom into areas of interest, and scale the graph's vertices to reduce clutter.
Flexible Layout Use one of several "force-directed" algorithms to lay out the graph, or drag vertices around with the mouse. Have NodeXL move all of the graph's smaller connected components to the bottom of the graph to focus on what's important.
Easily Adjusted Appearance Set the color, shape, size, label, and opacity of individual vertices by filling in worksheet cells, or let NodeXL do it for you based on vertex attributes such as degree, betweenness centrality or PageRank.
Dynamic Filtering Instantly hide vertices and edges using a set of sliders—hide all vertices with degree less than five, for example.
Powerful Vertex Grouping Group the graph's vertices by common attributes, or have NodeXL analyze their connectedness and automatically group them into clusters. Make groups distinguishable using shapes and color, collapse them with a few clicks, or put each group in its own box within the graph. "Bundle" intergroup edges to make them more manageable.
Graph Metric Calculations Easily calculate degree, betweenness centrality, closeness centrality, eigenvector centrality, PageRank, clustering coefficient, graph density and more.
Task Automation Perform a set of repeated tasks with a single click.

NodeXL for Programmers

The NodeXL template displays graphs using a custom Windows Presentation Foundation (WPF) control that can be reused in custom applications. In fact, the template is just an application wrapper around a set of reusable, prebuilt class libraries. Check the Downloads tab for the latest version of the class libraries.

You can create a .NET assembly that will import graph data from a custom source into the NodeXL template. These "plug-ins" appear in NodeXL's Data, Import menu. See For Programmers: About NodeXL Graph Data Providers for details.

Updated Wiki: CompleteReleaseHistory

tcap479 — Sat, 18 May 2013 19:03:38 GMT

Complete NodeXL Release History

1.0.1.243 (In progress, private release)

The Twitter Search Network now uses experimental shared term thresholds. This is part of an effort to derive meaningful edge results without running into Twitter's new rate limits.

1.0.1.242 (2013-05-01, private release)

The shared word user threshold can now be specified in the network configuration file used by the Network Server program. (For advanced users of private releases only.)
Bug fix: If you specified shared hashtag, URL, word, or word pair edge relationships in the Import from Twitter Search Network dialog box, the graph summary (NodeXL, Graph, Summary) did not mention the fact that the graph included those edges. (Private releases only.)

1.0.1.241 (2013-04-25, private release)

Bug fix: If you imported a Twitter network that included the empty hyperlink "http://" somewhere in the network's text, Excel would refuse to save the workbook. The error message started with "Errors were detected while saving..." This is an Excel bug that will also arise if you type "http://" directly into a cell. This change does not fix the latter problem.

1.0.1.240 (2013-04-24, private release)

If you check "add statistic columns to the Vertices worksheet" in the Import from Twitter Search Network dialog box, no additional time will be required to get the network. This used to require additional Twitter requests, and it was marked as "slower" in the dialog box.

1.0.1.239 (2013-04-08, private release)

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

1.0.1.237 (2013-03-25, private release)

Same as 1.0.1.236, but with additional edge options.

1.0.1.236 (2013-03-25)

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.
If you set the Visibility of vertex X to "Skip" and vertex X has adjacent vertices that are connected only to vertex X, then those adjacent vertices are now skipped as well. Previously, the adjacent vertices would remain in the graph as isolates.

1.0.1.234 (2013-01-25, private release)

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.

This assignment was created by Derek Hansen for BYU's IT 515R: Web and Social Media Analytics course. Students work on this for several weeks. Ideally they will first get feedback from peers and the instructor on the goals of their analysis and the data they'll be using. Next they create a draft visualization that is shared with their classmates and the instructor for feedback. Finally, they present the results to the class and post them to the NodeXL Graph Gallery (after anonymizing data if it is private).

Complete NodeXL Release History

1.0.1.242 (2013-05-01, private release)

The shared word user threshold can now be specified in the network configuration file used by the Network Server program. (For advanced users of private releases only.)
Bug fix: If you specified shared hashtag, URL, word, or word pair edge relationships in the Import from Twitter Search Network dialog box, the graph summary (NodeXL, Graph, Summary) did not mention the fact that the graph included those edges. (Private releases only.)

1.0.1.241 (2013-04-25, private release)

Bug fix: If you imported a Twitter network that included the empty hyperlink "http://" somewhere in the network's text, Excel would refuse to save the workbook. The error message started with "Errors were detected while saving..." This is an Excel bug that will also arise if you type "http://" directly into a cell. This change does not fix the latter problem.

1.0.1.240 (2013-04-24, private release)

If you check "add statistic columns to the Vertices worksheet" in the Import from Twitter Search Network dialog box, no additional time will be required to get the network. This used to require additional Twitter requests, and it was marked as "slower" in the dialog box.

1.0.1.239 (2013-04-08, private release)

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

1.0.1.237 (2013-03-25, private release)

Same as 1.0.1.236, but with additional edge options.

1.0.1.236 (2013-03-25)

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.
If you set the Visibility of vertex X to "Skip" and vertex X has adjacent vertices that are connected only to vertex X, then those adjacent vertices are now skipped as well. Previously, the adjacent vertices would remain in the graph as isolates.

1.0.1.234 (2013-01-25, private release)

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.

Complete NodeXL Release History

1.0.1.242 (In progress, private release)

The shared word user threshold can now be specified in the network configuration file used by the Network Server program. (For advanced users of private releases only.)
Bug fix: If you specified shared hashtag, URL, word, or word pair edge relationships in the Import from Twitter Search Network dialog box, the graph summary (NodeXL, Graph, Summary) did not include the fact that the graph included those edges. (Private releases only.)

1.0.1.241 (2013-04-25, private release)

Bug fix: If you imported a Twitter network that included the empty hyperlink "http://" somewhere in the network's text, Excel would refuse to save the workbook. The error message started with "Errors were detected while saving..." This is an Excel bug that will also arise if you type "http://" directly into a cell. This change does not fix the latter problem.

1.0.1.240 (2013-04-24, private release)

If you check "add statistic columns to the Vertices worksheet" in the Import from Twitter Search Network dialog box, no additional time will be required to get the network. This used to require additional Twitter requests, and it was marked as "slower" in the dialog box.

1.0.1.239 (2013-04-08, private release)

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

1.0.1.237 (2013-03-25, private release)

Same as 1.0.1.236, but with additional edge options.

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.

Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.

Complete NodeXL Release History

1.0.1.241 (In progress, private release)

Bug fix: If you imported a Twitter network that included the empty hyperlink "http://" somewhere in the network's text, Excel would refuse to save the workbook. The error message started with "Errors were detected while saving..." This is an Excel bug that will also arise if you type "http://" directly into a cell. This change does not fix the latter problem.

1.0.1.240 (2013-04-24, private release)

If you check "add statistic columns to the Vertices worksheet" in the Import from Twitter Search Network dialog box, no additional time will be required to get the network. This used to require additional Twitter requests, and it was marked as "slower" in the dialog box.

1.0.1.239 (2013-04-08, private release)

Same as 1.0.1.238, but with additional edge options.

1.0.1.238 (2013-04-08)

Bug fix: In versions 1.0.1.236 and 237, if you entered a space (or a colon, or a few other special characters) into the "Add a vertex for each..." textbox on the Import from Twitter Search Network dialog box, you would get a message that included the text, "The Twitter Web service refused to provide the requested information."

1.0.1.237 (2013-03-25, private release)

Same as 1.0.1.236, but with additional edge options.

1.0.1.236 (2013-03-25)

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.
If you set the Visibility of vertex X to "Skip" and vertex X has adjacent vertices that are connected only to vertex X, then those adjacent vertices are now skipped as well. Previously, the adjacent vertices would remain in the graph as isolates.

1.0.1.234 (2013-01-25, private release)

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.

Same as 1.0.1.236, but with additional edge options.

1.0.1.236 (2013-03-25)

There are some major changes in NodeXL's Twitter importers. See Changes in NodeXL's Twitter Importers for more information.
When you use dynamic filters (NodeXL, Analysis, Dynamic Filters), filtering an edge will automatically filter its adjacent vertices if the filtering causes those vertices to become isolates.
If you set the Visibility of vertex X to "Skip" and vertex X has adjacent vertices that are connected only to vertex X, then those adjacent vertices are now skipped as well. Previously, the adjacent vertices would remain in the graph as isolates.

1.0.1.234 (2013-01-25, private release)

There are some new edge options in the Import from Twitter Search Network dialog box.

1.0.1.233 (2013-01-19, private release)

In the Export to Email dialog box, (NodeXL, Data, Export, To Email), there is a new button for inserting a sample message.
When you import a set of GraphML files into a set of new NodeXL workbooks (NodeXL, Data, Import, From GraphML Files), a bad GraphML file will no longer stop NodeXL in its tracks. Any bad GraphML files are now reported after all the good GraphML files are imported.
There are some new edge options in the Import from Twitter Search Network dialog box.
Bug fix: If you entered an Image File value on the Vertices worksheet that included an invalid character, such as a less-than sign, you would get an error message that included the text "[ArgumentException]: Illegal characters in path". Now there will be no error message, and instead an image of a red X will be shown in the graph pane.
Bug fix: If you automated a workbook (NodeXL, Graph, Automate), checked "save workbook to a new file if it has never been saved," and the specified folder to save the workbook to didn't exist, you would get an error message that included the text "[COMException]: Microsoft Office Excel cannot access the file...". Now you get a message telling you how to fix the problem.
Bug fix, for programmers only: If you colored vertices by using the System.Windows.Media.Color type for ReservedMetadataKeys.PerColor values, you created groups, and then you collapsed a group, you would get an ArgumentException with the message "The value with the key "~PDColor" is of type System.Windows.Media.Color. The expected type is System.Drawing.Color." This did not occur if you used the System.Drawing.Color type.

1.0.1.230 (2012-12-07)

If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), the graph summary (NodeXL, Graph, Summary) now includes the actual number of Twitter users in the network, not just the maximum number.
If you autofill the group label column (NodeXL, Visual Properties, Autofill Columns), you can now tell NodeXL to prepend the group name to the group label.

1.0.1.229 (2012-11-25)

The maximum Size value in the Vertices worksheet has been increased from 100 to 1,000, so NodeXL will make the vertices in the graph pane much larger if you tell it to.
When you use what is commonly called "group in a box" (NodeXL, Graph, Layout, Layout Options, "Lay out each of the graph's groups in its own box), the boxes now have less contrast with the graph background, so they don't stand out as much.
If you export the graph to email (NodeXL, Data, Export, To Email), you can now include HTML markup in the email's message, and you can place a graph summary or an image of the graph anywhere in the message.

1.0.1.228 (2012-11-19, private release)

NodeXL will now group the graph's vertices by motif. Motifs are a new way to reduce the visual complexity of your graph. With motif simplification, common repeating network motifs are replaced with easily understandable glyphs that require less space, are easier to understand, and reveal hidden relationships. Go to NodeXL, Analysis, Groups, Group by Motif. (This work was done by Cody Dunne and Ben Shneiderman at the University of Maryland.)
Bug fix: If you used the NodeXL Network Server program to import a Twitter network, the graph summary did not include any data import details. The data import details are now always included when the NodeXL Network Server program is used.

1.0.1.227 (2012-11-13, private release)

The way the Size column on the Vertices worksheet affects the actual size of Image vertices in the graph pane has been changed. The range of actual Image vertex sizes was too large before; now it has been compressed into something more sensible.
If you automate the graph (NodeXL, Graph, Automate), there is a new option for automatically exporting the graph to the NodeXL Graph Gallery.
If you automate the graph, there is a new option for automatically exporting the graph to email.
If you export the graph to email, the email is now in HTML format and includes an embedded image of the graph.
You can now enter a longer description when exporting a graph to the NodeXL Graph Gallery or to email.
The order of items in the graph summary (NodeXL, Graph, Summary) has been changed: The "Groups" item now comes immediately after the "Graph type" item.
The order of items in the Twitter Search Network Top Items worksheet (and in the graph summary) has been changed: The "Top Replied-To" and "Top Mentioned" items now come immediately before the "Top Tweeters."
Each column in the Twitter Search Network Top Items worksheet is now only as wide as the longest column name in the column. The column used to be as wide as the longest cell contents in the column, which made the column too wide when the cells contained URLs, for example.
Bug fix: If you entered an invalid email address in the Export to Email dialog box, you would get an ugly error message that included the text "FormatException." You now get a message that makes sense.
For programmers: Several benign build warnings involving XML documentation have been fixed. (These warnings showed up only in Visual Studio 2010, not 2008.)

1.0.1.226 (2012-10-16)

You can now email your graph directly from NodeXL. Your email can include the NodeXL workbook and the graph data as GraphML. Go to NodeXL, Data, Export, To Email.
If you export a large graph to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery) and you include the graph data as GraphML, the export is now much faster. (The GraphML is now zipped before it is exported).
You can now export your graph to a GEXF file. (GEXF is a file format used by the Gephi program.) Go to NodeXL, Data, Export, To GEXF file in the Excel ribbon.
The "Import from YouTube Video Network" feature (NodeXL, Data, Import) no longer offers an "add an edge for each pair of videos tagged with the same keyword" option, because YouTube will no longer provide programs like NodeXL with keyword information. It has been replaced with an "add an edge for each pair of videos that have the same category" option.
The "Import from YouTube User's Network" feature no longer offers an "add a vertex for each friend of the user" option. YouTube will no longer provide this information.
If you group the graph's vertices by motif, you can now group by clique motifs in addition to fan and D-parallel motifs. (This work was done by Cody Dunne at the University of Maryland.)
If you use the Network Server program to import networks into GraphML files, and you then import the GraphML files into NodeXL workbooks using NodeXL, Data, Import, From GraphML File or From GraphML Files, the data import details ("The graph represents a network of up to 100 Twitter users...") are now preserved.
For programmers: The NodeXL source code is now available on the CodePlex "Source Code" tab. The source code will no longer be provided as separate releases on the Downloads tab.
