[Matrix-SIG] Rose plotting widjet?

[Michael Bell]

I need to plot some wind-roses.  Has anyone developed one themselves,
or know of where one may be found?

[A wind-rose is a plot of wind speed distribution versus direction. It
looks vaguely flower-like, where each petal in some fashion presents
the distribution of some quantity, usually speed, in that direction.]

My Tkinter code is very ugly, and I'd rather use someone else's if it
already exists.

Thanks,
