Source and Download

You can check out the source for GraphvizPlugin from Subversion at http://trac-hacks.org/svn/graphvizplugin.

Or you can download the zipped source from here. Note that this contains everything regarding the Graphviz plugin including tagged releases and branches. The 0.10 directory contains the latest released version of the code for Trac 0.10 and the 0.11 directory contains the latest code for Trac 0.11.

• download latest stable version (0.7.5) for Trac 0.11
• download latest version for Trac 0.10

That version has some trouble with rsvg support for creating anti-aliased images. The upcoming version contains a few related fixes:

• download latest unstable version (0.7.6dev) for Trac 0.11

If you want to have anti-aliased images, it might be a better option anyway to get/build a recent version of graphviz tools, which support producing anti-aliased images directly (through pangocairo support).

Example

{{{
#!graphviz
digraph G {Hello->World->Graphviz->Rules}
}}}

would produce an image like:

Note that you can insert TracLinks like this:

{{{
#!graphviz
  digraph G {
    rankdir = "LR"
    GraphvizPlugin [ URL=GraphvizPlugin ]
    Trac [ 
      URL="http://trac.edgewall.org/"   
      fontcolor=red
    ]
    GraphvizPlugin -> Trac
    }
}}}

This produces an image like this, but with clickable nodes (note that nodes aren't actually clickable in this example):
