[Tutor] plot

[lina]

Hi,

I have not experienced in "plot a figure" with python.

Just wonder:

Try python-pygraphviz is a good choice?

http://pzwart3.wdka.hro.nl/wiki/PythonGraphviz

another question:

pygrphviz can achieve a better effect than the one on the wikipage,
such as can I change the round circle into something a bit
"processed", I mean, pentagon or something, or color the edge.

Thanks with best regards,
