Just some thoughts:
- I agree with Jason that ultimately, integrating a library specifically
focused on Python and web plotting is the best course for SymPy and
Gamma/Live in general.
- Gamma/Live's problem is that it runs on App Engine - anything that
requires a server won't work. (I think Bokeh/WebAgg fall into this
category, but I'm not sure. WebAgg also isn't available on App Engine yet
anyways.)
- WebAgg seems to render the plot on the server and send frames to
the client. Locally it ran at an acceptable (but slow) rate; I'm not
sure
how well this would hold up on App Engine.
- One of the reasons that Gamma uses its own plotting is because it
lets the user pan the plot and load more of the plot on demand.
- On mpld3: it would be nice to integrate just to support more plots,
but for 3D specifically it won't
help<https://github.com/jakevdp/mpld3/issues/69#issuecomment-34880654>
.
- On passing JSON data to the browser to render: this is what we do
already<https://github.com/sympy/sympy_gamma/blob/master/app/logic/resultsets.py#L583>
.
