Welcome!
This is the webpage for NetDraw, a Windows program for visualizing social network data. The program is free. But if you do use the program, please cite it. Here is the citation information:
Borgatti, S.P., 2002. NetDraw Software for Network Visualization. Analytic Technologies: Lexington, KY
Even though the program is continually updated, it seems better to leave the publication date alone so as to not confuse citation counters.
