I have used VCG for a number of compiler projects. It is described at


http://www.cs.uni-sb.de/RW/users/sander/html/gsvcg1.html


Graphs are defined in a straightforward text-based input format. The
tool can be used interactively or can output generated graphs as ".eps"
files (if you use this in earnest then see the patch on
http://www.cl.cam.ac.uk/~tlh20 which generally improves the size and
rendering time of the PostScript).


My experience has been that it is good at laying out control flow graphs
but not very good with more general structures. However, the input file
can provide various hints to the layout algorithm.


It is not a Java tool.
