This is off to a solid start.
What do you think about adding some structure to this so that components line resistors and meters are drawn by functions? The whole diagram drawing could then fit in a small "paragraph" of code which gives a high level overview of what is drawn and the functions contain the nitty-gritty details. That would also be a bit closer to how kiva code exists in the wild, at least in the context of Chaco tools and plot renderers.

"Whiting out" like this will work on pixel-based backends, but may not work on postscript/pdf backend. Check those to see what you get.
As a style guide, it's generally better to draw only the lines you want.

That makes sense, I had only considered the performance issue john mentioned, not that it might not even work. I don't think the example will work at all with postscript/pdf because we use draw_marker_at_points. Nonetheless, it might be worth adding a sentence saying not only that we generally wouldn't want to do this for performance reasons, but also that it may not even produce correct results if using a different backend.
I believe the advanced_tutorial.py should work, although I still need to try running it with different backends to make sure
