I made that branch for use in the Plot Activity for the Sugar Learning
Platform. I'm glad someone is using it!
I had planned on making some more changes to it (for one, cleaning up
the API to separate drawing code from data even better than it
currently is, and possibly adding interactive features), but I don't
really have much time to work on it this summer. It could definitely
use some cleaning up, for sure, but I did my best in making my changes
to avoid breaking compatibility with existing plots.
