Wgraph -- the mediawiki graph definition tool
Wgraph is a mediawiki extension which supports graph drawing. With Wgraph you define the semantics of a graph in an abstract textual notation called WGL (Wiki Graph Language). You may add hints for layout, but the graph itself will be produced automatically. Wgraph is a powerful visualisation instrument for objects and their relations. It is NOT a 'wysiwyg' drawing tool.

Graph layout is a very challenging task. Wgraph delegates most of this task to a brilliant product called aiSee. aiSee came out of the German university area 15 years ago and is now being marketed commercially by AbsInt, Saarbrücken, Germany. You can download a free 30-day trial version. Here are direct download links for your convenience:
- aiSee 2.2.28 for Windows (3.5MB)
- aiSee 2.2.28 for 32-bit Linux (1.9MB)
- aiSee 2.2.28 for 64-bit Linux (2.0MB)
- Other platforms
aiSee can be registered for free for non-commercial use. Non-commercial use is educational, academic research and private use. Non-commercial users can get a license key that extends the usage period of the trial version until February 14, 2009. After that you will have to download aiSee again (and the usage period will be extended for another year, provided the usage is still non-commercial).
The two modes to use Wgraph
Wgraph is an interface between mediawiki and aiSee. It hides aiSee completely from the eyes of the user and adds a small additional abstraction layer to make graph definitions even more comfortable than with native aiSee.
- The direct way to use Wgraph is to invoke the parser function #wgraph with your WGL code as a parameter.
- In combination with another mediawiki extension (called DPL: Dynamic Page List) you can even visualize structural aspects of your wiki as a wikigraph. In a wikigraph articles map to nodes, categories to nodetypes and relations are deduced from template calls.
With Wgraph you can view a graph definition from different angles. You can hide certain nodes / edges and emphasize others. You can group nodes to subgraphs and show them in a special surrounding box. There are several layout strategies to choose from. You control the graphical representation of nodes and edges using shapes, colors, linestyles, arrows and even bitmap images. To avoid redundancy and reach a higher level of abstraction you can take advantage of the built-in WGL type concept.
Graphs are produced in png and svg format. In addition there is a png thumb image. Apart from viewing the generated graph in the browser, aiSee can be used as a local client application. This gives enhanced possibilities of edge concentration, subgraph folding etc. Make sure that you comply to the licensing terms of AnsInt.
