Visualizing the Graphs

There is an existing Trac plug-in called GraphVizPlugin that might be of use to us. It takes in a DOT Language definition of a graph, and then exports an image of the graph, that is displayed on the Trac wiki page. You can customize the edge colours, and shapes of the nodes, and all sorts of other stuff. It requires that you have GraphViz installed on your system, though -- hopefully not a big deal.

Problem: I'm not sure if we'd be able to make the graphs interactive using this plugin. The plug-in can output image maps, so we should be able to make the graphs interactive. (For example, I'd want it to display information about "Bob" if you mouse-over Bob's node in the graph). I think GraphVizPlugin provides the easiest (but not prettiest!) way to visualize the graphs. I think I'll keep looking for other options.
