I suppose, but SVG is a vector graphic format -- to fully support it you
need to write a LOT of code. Which folks have worked on, though I don't
think any of those efforts are complete.

well, then you pretty much have your program :-)

Your best bet is probably to do what Jupiter is doing -- i.e. rendering
with a browser.

You can embed the system browser in a wxPython app:

Or the Chrome embedded framework:

Another option is to use an external SVG renderer, like Inkscape, and have
it render PNGS, and then load those up in wx. Really kludgy but with modern
fast computers, probably good enough!
