I am proud to give you a plugin for displaying force directed graph layouts
The main code was written by my colleague Marvin (who is by now a web2py adept). I wrapped it into a plugin. So far I found only two js packages that can do force directed graph layouts: http://jsviz.org/ (no proper interface) and http://thejit.org/ (only in the vc repo, no attribute to configure the edge length) This plugin has the missing features. The data object syntax is compatible to thejit, if you visit http://127.0.0.1:8000/YOURAPP/plugin_forcedirected/index you will find some documentation Enjoy screenshot: http://jaguar.biologie.hu-berlin.de/~fkrause/screenshot_forcedirected.png download: http://jaguar.biologie.hu-berlin.de/~fkrause/web2py.plugin.forcedirected.w2p Feedback, positive and negative is welcome!
