matplotlib (http://matplotlib.sf.net) has several examples showing how
to do animation.  See anim.py, anim_tk.py, system_monitor.py,
dynamic_demo.py, dynamic_demo_wx.py in
http://matplotlib.sf.net/examples.

They aren't blindingly fast, but they work.

If you need blindingly fast, you don't have a lot of great options
(yet).  See the recent thread
