Florian -

Graphviz (http://www.graphviz.org) is a great package for drawing 
graphs.  It ouputs to many formats.  There is a python lib for it at 
http://www.freshports.org/graphics/py-graphviz/, but I have not used 
it.  It's easy enough to generate dot[1] code and call dot to generate 
the graph image, so that's what I usually do.

HTH,

Bill


1. 'dot' is one of the graphviz commands.
