First ensure that graphviz is installed on the server: yum install graphviz

Copy Graphviz and SiteGraph from klaus.ede.hih.au.dk/extensions to the local extensions directory

Add these lines to LocalSettings:

# To enable the Graphviz utility - by KK 2009 11 21
include("extensions/Graphviz/Graphviz.php");
$wgGraphVizSettings->dotCommand = "/usr/bin/dot";
 
# To enable the SiteGraph utility - by KK 2009 11 21
require_once("$IP/extensions/Graphviz/Graphviz.php");
require_once("$IP/extensions/SiteGraph/SiteGraph.php");

Use this code in the wiki page to display the graph over the wiki:

<sitegraph type="digraph" layout="neato">
graph [
  center=true,
  fontname="Verdana",
  bgcolor="transparent",
  truecolor="true",
  fontsize=12,
  overlap="orthoyx",
  splines="true",
  pack="true",
  sep="0.1",
  dpi=62,
  ratio="compress",
  epsilon="0.001",
];
 
edge [
  fontsize=10,
  arrowsize=0.5,
  len=0.5
];
 
node [
  fontsize=12,
  shape="ellipse",
  height=0.25,
  width=0.25,
  fontcolor=blue,
];
</sitegraph>

Hint: Use ?action=purge at the end of the URL to refresh the graph immediately.
