The SiteGraph extension is part of the MediaWiki extensions I created to make this site more useful. Here is the graph of the articles in my wiki:
<sitegraph type="digraph" layout="sfdp"> graph [
center=true,
fontname="Verdana",
bgcolor="transparent",
truecolor="true",
fontsize=12,
overlap="false",
rank="TB",
splines="true",
pack="true",
sep="0.1",
dpi=62,
ratio="compress",
epsilon="0.001",
];
edge [
fontsize=12,
arrowsize=0.5,
len=0.5
];
node [
fontsize=12,
shape="plaintext",
height=0.25,
width=0.25,
fontcolor=blue,
]; </sitegraph>
