    v52 v53  
    99This is a plugin that allows the dynamic generation of diagrams by [http://www.graphviz.org/ Graphviz] programs. The text of a wiki page can contain the source text for Graphviz and the web browser will show the resulting image.

    11 For examples, see below.
     11For example, add the following lines to a wiki page:
     12
     13{{{
     14{{{
     15#!graphviz
     16digraph G {Hello->World->Graphviz->Rules}
     17}}}
     18}}}
     19
     20and that would produce an image as follows:

     24Note that you can insert TracLinks like this:
     25{{{ 
     26{{{
     27#!graphviz
     28  digraph G {
     29    rankdir = "LR"
     30    GraphvizPlugin [ URL=GraphvizPlugin ]
     31    Trac [
     32      URL="http://trac.edgewall.org/"   
     33      fontcolor=red
     34    ]
     35    GraphvizPlugin -> Trac
     36    }
     37}}}
     38}}}
