How to export LaTeX snippets to HTML via SVG rather than PNG?

Question

The org-mode source

#+OPTIONS: toc:nil creator:nil author:nil timestamp:nil num:t validate:nil
#+OPTIONS: tex:imagemagick
#+LaTeX_HEADER: \usepackage{tikz}

\begin{tikzpicture}
   \draw (0,0) circle (3cm);
\end{tikzpicture}

exports to HTML like a charm. However, the LaTeX snippet is converted to PNG format. Is there a simple way to persuade the system to use SVG rather than PNG?

Answer 1

By default the exporter uses Mathjax. You are explicitly over-riding this with the tex:imagemagick option, which uses PNG instead. The option tex:dvisvgm selects svg format.
