Produced by RTGI Labs and Gephi team, it was initially discussed in a talk at the FPW’09.</p> <p>You can download original graph source files from each subproject page.<br /> Available formats are: GEXF (Gephi graph format), GDF (Guess graph format), SVG, and PDF.<br /> For some of the subprojects, an embedded javascript visualization is also available.

The good news you could use a Linux VM to display the 3d rendering.</p> <p>It can be accessed with Python via XML RPC in a way that is trivially easy.</p> <p>You might want to look into <a href="http://www.secdev.org/projects/rtgraph3d/" rel="nofollow">http://www.secdev.org/projects/rtgraph3d/</a> as well. It is the graph lib used for <a href="http://www.secdev.org/projects/ipv6world/" rel="nofollow">http://www.secdev.org/projects/ipv6world/</a> which renders large networks.</p> <p>I doubt you can get either to run in Windows. But, both of these programs are worth at least the effort of setting up a Linux VM. If you have no considered it before, try to setup a VM with <a href="http://www.virtualbox.org" rel="nofollow">http://www.virtualbox.org</a> which is a decent opensource virtualizer, with 3d acceleration. Try that with a distro like Ubuntu, and you would be surprised how easy it is to use.</p> <p>Good Luck! </p> http://forums.flowingdata.com/topic/large-network-layout-and-visualization#post-644 Tue, 21 Apr 2009 17:32:23 +0000 i2pi 644@http://forums.flowingdata.com/ <p>You may want to try using igraph from within R.
