More code is always interesting.  Is it available somewhere?

Here is the equivalent code in the idemponit tool:

https://github.com/IETF-Formatters/html-rfc/blob/master/nits/formula.js


In HTML, you create a tag like this:

<img class='formula' alt='[LaTeX]'>

And the tool uses Google Charts to render a .png and include it inline in
your document.

A worked example can be found here:

Note to folks who still need help with intuition about embedding images
with RFC 2397 data URLs (sic), please view-source on that section.
