Good thing there is a platform independent Python graphics library!
PIDDLE (Plug In Drawing, Does little Else) at
There is a discussion list at www.egroups.com/pythonpiddle/
PIDDLE is pretty stable, and we hope we'll build up a bunch of such
applets on top of it over time.
BTW, I'm in charge of the PDF back end for PIDDLE, and would certainly
have uses for such a routine. One demo I've always wanted is to look
at a Python program and draw a module dependency graph (as well as all
the module docstrings)....
