Hi, thanks for the links, I found an example of drawing a graph here
too, based on the pysketch sample app included with wxpython. It's
rough but it is simple enough to learn from. It even has some code to
load and save graphs in GXL: http://www.cc.jyu.fi/~minurmin/ai/
Other basic graph code, without the drawing part:
