[matplotlib-devel] html5/canvas interactive backend

A few weeks ago, Fernando pointed out the new canvas backend to gnuplot:

Is there anyone that has worked on anything similar in matplotlib, i.e.,
a backend that would provide the interactive features of the GUI
backends in a web browser?  Over in the Sage project, we are very
interested in something like this.  While I can't volunteer at the
moment to write something like a canvas backend for matplotlib (or maybe
an interactive svg backend using javascript as well), I'm interested in
working on this as I have time.  We also might have other people in the
Sage project interested in working on this, though we'd have to come up
to speed on implementing a matplotlib backend first.

Thanks,

Jason
