Extension:GraphViz

The GraphViz extension is a MediaWiki extension. When used with the Semantic Result Formats extension, it lets you create and display graphs as inline images on wiki pages, using the open-source Graphviz and Mscgen applications:
 * Graphviz is a program that allows the creation of numerous types of graphs, using the DOT language.
 * Mscgen is a small program that parses Message Sequence Chart descriptions. Unlike Graphviz, this program does no clever layout operations or spline routing, as this is not needed.

Additionally, this extension supports multiple graphs on one page, wiki-links in graphs, and automatic pruning of old images.
