Extension:Diagrams

The Diagrams extension displays GraphViz, Mscgen, and PlantUML diagrams in a wiki. It can be configured to use a small web service to render the images.

It replaces the and  extensions in some ways, but does not (yet) support all features of either of them. The primary reason for a different extension is to not store the rendered images as wiki files.

Optional external rendering
This extension can also be configured to use an external rendering web service to generate the actual diagrams files. This is useful if you do not want the rendered files to be stored in the wiki, or if you have security requirements that make it more convenient to have the external rendering commands run somewhere other than on the web server.

There are two implementations of the service:


 * 1) A PHP (Symfony) based service – installation instructions
 * 2) A Python based service – installation instructions, demo

Once you have the servicing installed and running correctly, add the following to your LocalSettings.php:
