There are a couple of graph visualization tools out there
but I'm not sure if they currently support Java interfaces.


graphviz/dotty from AT&T:
http://www.research.att.com/sw/tools/graphviz/


VCG (Visualization of Compiler Graphs):
http://www.cs.uni-sb.de/RW/users/sander/html/gsvcg1.html




I've used dotty more than VCG (and it was for visualizing
CFGs of methods in a Java compiler) and I found it adequate
for my purposes, though it sometimes tends to lay out things contrary
to the sequential order of basic blocks in the CFG. It does
take layout hints from the user but I was too lazy to use
them ...
