@DayuanJiang, I ended up just nesting a whole bunch of matrices: ```latex $$\begin{matrix} & \begin{matrix}A&C&G&T\end{matrix} \\\\ \begin{matrix}A\\\\C\\\\G\\\\T\end{matrix} & \begin{pmatrix}1&2&3&4\\\\3&4&5&6\\\\3&4&5&6\\\\3&4&5&6\end{pmatrix}\\\\ \end{matrix}$$ ``` which yields:  It's not perfect but hopefully close...

@DayuanJiang, you may already know this but the extra backslashes are a workaround for displaying MathJax in HTML (see http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-in-html-documents).

Yes I'm using revealJS with Markdown. I was going to elaborate but then figured it was too much info :)

Wow I'm so old that I was trying to run the CLI the ancient way. Thanks for the correction :-)

Specifically, this is for the `rooted.js` and `rtt.js` animations on the Trees page.
