 #### LaTeX Typesetting
 
-Figure titles, axis labels and annotations all accept LaTeX directives for rendering mathematical formulas and notation, when the entire label is surrounded by dollar signs `$...$`. This rendering is handled by the [MathJax library](https://www.mathjax.org/) (version 2.7.5), which must be loaded in the environment where figures are being rendered. MathJax is included by default in Jupyter-like environments, but when embedding Plotly figures in other contexts it may be required to ensure that MathJax is separately loaded, for example via a `<script>` tag pointing to a content-delivery network (CDN).
