# How to view math symbols at this url

I see lines like the following at https://plotly.com/python/v3/alpha-shapes/

Let $S$ be a finite set in $\mathbb{R}^d$, $d=2,3$ (i.e. a set of 2D or 3D points).

What is it? MathML or embedded latex or something else? Do I need an extension to view it? I have already tried chrome, edge, firefox, opera on windows. I looked at the html of the page I see use of the term mathjax.

• FWIW, I also only see the markup (that is, not the intended result) in the latest version of Firefox (109.0.1, 64-bit) on Windows 7. Feb 5 at 12:43

• Replying with 109.0.1 (64 bits) on Mac OS X here, and things like $\mathbb{R}^d$ aren't converted (and I'm happy the HTML is respected.) Check if you don't have some nifty extension @Hannu Maybe TeX.Zilla? Feb 5 at 15:18
