I like the look of the VCG grammer. It seems a little more elegant than GraphViz.
The graphs themselves are not quite as pretty but, choice is a good thing.
Hopefully I can release a new version of autodia soon - new stuff will include better graphviz support so that it will output jpg if your file is filename.jpg or jpeg, same for gif, png and dot.
oh yeah - heres the url for vcg : http://rw4.cs.uni-sb.de/users/sander/html/gsvcg1.html
