I am using graphics/graphviz, http://www.graphviz.org/, for graphs
drawing. It uses an input .dot file containing the graph description
and produces a image (.jpg or .ps) with the visual representation of
the graph. I used to generate those .dot files from the data in my
programs and process them with graphviz. I am not sure that may be it
even exports API to be directly called.
