You're quite right to pull me up on this. In fact, I've not tested chaco
for this type of application so I can't say for sure if it's fast enough
or not. I guess, my expectation was that it would not be much faster
than matplotlib (given they both use Antigrain for rendering, which
tends to be the bottleneck). Whenever I tried any type of anti-aliased
drawing (antigrain or cairo) there is always a significant performance
hit (on linux anyway).

Sounds like I should revisit chaco (I haven't tried it in a while).
My main problem with it is lack of documentation (this is really what
has prevented me from testing it extensively).
