Thanks for mentioning these. I didn't know about them. Do you know if there is any good charting higher abstractions for "node" graphs (http://en.wikipedia.org/wiki/Graph_(abstract_data_type))? I only know about the force layout ones in d3.

Nevermind, I found this: http://stackoverflow.com/questions/7034/graph-visualization-...

(Although I'm still lokking for a good tool for visualizing path algorithms (TSP, A* etc))
