That does look like what I'm after.  Two things are unclear to me from the docs you pointed to:
1) How do you actually add something to a plot with those?  Are they automatically added to the current figure just by creating them?
2) How do patch/poly collections determine the edges?  All I can see in the docs is a mention of a list of verts, but not any mention of how you specify edges.

Thanks,

Bill,

I'm not totally sure if it will help for this, but try checking out

matplotlib.collections.LineCollection
and
matplotlib.collections.PolyCollection

http://matplotlib.sourceforge.net/matplotlib.collections.html
