+Nodes on the graph can link to external urls using regular graphviz syntax,
+and a clickable imagemap will be created. As a special extension for
+ikiwiki, [[WikiLinks|ikiwiki/wikilink]] can also be used. For example:
+
+ \[[!graph src="""
+ google [ href="http://google.com/" ]
+ sandbox [ href=\[[SandBox]] ]
+ help [ href=\[[ikiwiki/formatting]] ]
+ newpage [ href=\[[NewPage]] ]
