Has anyone ever worked on a backend that generates javascript code for

Alternatively, I suppose we could generate an svg or html5 plot and then
accompany it with the javascript code to trace the function, etc.

So maybe pyjamas or pyjs might help?
http://pyjs.org/
http://stackoverflow.com/questions/683462/best-way-to-integrate-python-and-javascript
gives a few other python->javascript compilers. I don't know if any are
