how to disperse the vertices

hi~all
At first, I have about 10000 vertices and more than 18000 edges.
The vertices near very each other and the graph seems too complicated.
Then, I adjust the groups and betweenness try to make the graph simple.
But some vertices still near each other although the other vertices have been hidden .
I am tried of moving the vertices manually again and again.
Does the Nodexl have some easier way to make the vertices more dispersion?

The other question is about save images.
When I click the item "save images" and select a folder to save , the image files always disappeared.
How to solve this problem?

Thank you for your interest in NodeXL.

Large graphs can be difficult to visualize since they can be too crowded.

NodeXL can perform several operations that can improve the visual display of a network.

You can apply

NodeXL>Analysis>Groups>Group by Cluster

NodeXL Graph Pane>Layout Menu>Layout Options>Layout each of the graph's groups in its own box and sort the boxes by group size

[ ] Use the Grid layout for groups that don't have many edges

Reduce the "Scale" slider all the way to the left

Apply the Harel-Koren layout

You can also remove some vertices and edges using the Visibility column in the Edges and Vertices worksheets.

You can collapse some groups to a single "meta" vertex to simplify the network.

Typically, only a few thousand nodes can be meaningfully displayed on a typical computer screen.

There is no reason that images are not being saved: can you try saving to a different location (desktop?) to confirm that images are not being created? You can also right-click the graph pane and capture the image to the clip board to be pasted into another application.
