This could be implemented by extending sympy's code generation to also generate JavaScript (we already do C and Fortran). Then we would need to use some JavaScript library that implements the mathematical functions. It might not be easy to do for some special functions that do not (yet) have a JavaScript implementation, but for most elementary functions this should work great, and it should allow the plot to be a lot more responsive.

Yes, we should probably move to Flask or some other lightweight framework. I also heard good things about ReactJS (which was not available when I started sympy gamma). Mvnnn, if you are interested, I think the above would be very useful improvements to sympy gamma.
