As Matplotlib seem not to work (what a drag it's such a nice tool) I'am looking for alternatives to create graphs while running python with ArcGIS 10. Besides regular pie and column charts I need in particular the possibility to create star plots/ radar charts / amoeba diagram - most likely something like:

http://matplotlib.sourceforge.net/examples/pylab_examples/polar_bar.html

Most likely with a tool with as less as possible dependencies. Any recommendations are welcome

Thanks!
