WP Render is a Wordpress Plugin to render math terms given in (La)TeX-, graphs given in GraphViz-, and plots given in GnuPlot-notation into SVG and PNG image files, embedding them into WordPress-posts and -pages. It is based on WP LaTeX by Automattic which is released under the under GPLv2.

It differs from WP LaTeX in that it had support for SVG, GnuPlot, and GraphViz added, as well as a few other bits of code changed. You will need pydvi2svg for the TeX->SVG rendering.

This plugin is not safe to install for blogs whose users you do not trust with a shell-account, and is definitely not safe to enable rendering in public comment areas. Furthermore, it has first and foremost been adapted to be used on this site. While there are not many additional assumptions made about your installation and most things are tweakable in the option interface, I have not invested much time into testing it in other contexts. This is not likely to change, either. You have been warned.

Usage examples can be found in Rendering TeX & Graphs to SVG in WordPress.
