hi there


VCG (http://www.cs.uni-sb.de/RW/users/sander/html/gsvcg1.html) or
graphviz that you have already mentioned seem to be close to what you
want. The graph syntax is easy to understand and I have written simple
backend generators for such graphs in software projects of mine. For
example, printing out data dependence graphs (as in compiler-generated
information) etc.


Maybe the daVinci tool is good as well.
