It turned out that just adding: interactive(False) before the drawing loop, and show() after it, sped things up tremendously. Instead of 5 minutes, it now takes about 2 seconds for the map to render. Which, ironically, is much more "interactive" :) Thanks for the pointer to LineCollection though. I'd never seen that.
