        \[[!graph src="a -> b -> c; a -> c;"]]
 

-Note that graphs will only show up in previews if your browser has
-[[!wikipedia data: URI]] support, or if the same graph already exists on that
-page.
+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]] ]
