You can use LaTeX in some visualizations (pretty much anywhere you are allowed to have HTML, here's an example:
http://jsfiddle.net/asgallant/3SeEe/). You can't add it to a chart area (as, for example, a label for a line) or anywhere else where HTML is not allowed. You could put the equation in a standard HTML div and use CSS to position the div over the chart, though.
None of this is enabled by the Visualization API - you have to use 3rd party tools to render the LaTeX (my example uses Mathjax).

I used to use the chart api for creation o images from latex format, like this:
http://chart.apis.google.com/chart?cht=tx&chf=bg,s,FFFFFF00&chco=AACCFF&chl=i\hbar\frac{\partial}{\partial t} \Psi(\mathbf{r},\,t) = \hat H \Psi(\mathbf{r},t)
But now it is deprecated. The new svg api support math annotation in latex format? If not, what are the guidelines for writing math symbols using chart api?
