Please advise good resources/books on NodeXL API.
I see that API is briefly mentioned in NodeXL book on Amazon (only 4 pages?). http://www.amazon.com/Analyzing-Social-Media-Networks-NodeXL/dp/0123822297
Also there is new book on graph viz and analysis
http://www.amazon.com/Graph-Analysis-Visualization-Discovering-Opportunity/dp/1118845846/
NodeXL is mentioned among top tools for graph viz and analysis, but most probably API is not covered.
