Lots of crazy ideas where given to me after my talk at the GraphViz,
including:

  o Graphing Perl code blocks
  o Graphing Perl 6 RFCs
  o Graphing regular expressions as a state machine
  o Outputing GraphML
  o Graphing databases
  o Output a graph to ASCII
  o Graphing the symbol table
  o Producing a SOAP interface to this module
  o Graphing RDF

Getting back the coordinates of graph nodes and edges is planned, too
;-)
