Add support for MathJax to render math expressions

[dataopt]

The schoolbook example has non-Tex-looking math expressions. Perhaps finding a way to use something like MathJax to render math formulas will help improve the look of math expressions.

Do you have an example of some tex Text I can render as a test?

Try this: Euler's formula: \(e^{i\pi} +1 = 0\)

Had a look at doing this and it would be a tough slog to get mathjax working inside svg that has been rendered by diagrams.
