There is Graphviz written by Leon Brocard. This is a Perl front-end to ATT Graphviz. I used the later and it works well for graphs of moderate complexity; I mean by that graphs that can be transformed to forests by removing a few edges.

I have no personal experience of the frond though and don't know if you can generate image-maps. But, I once generated a representation of perl grammar using ATT graphviz.
