Graph-ReadWrite 1.00 is currently making its way round CPAN:

          file: $CPAN/authors/id/N/NE/NEILB/Graph-ReadWrite-1.00.tar.gz
          size: 7027 bytes
           md5: d7883fd4e9f396decd777949e21bac2b

This is a collection of perl classes for reading and writing directed graphs in 
a variety of file formats. The graphs have to be represented using Jarkko's 
Graph classes.

The bundle currently includes:

        Graph::Reader, Graph::Writer    base classes
        Graph::{Reader,Writer}::XML     a simple XML format for graphs
        Graph::Writer::Dot              format used by dot [1]
        Graph::Writer::VCG              format used by VCG [2]

[1] dot is a tool for batch layout of graphs, part of the
    graphviz toolkit from AT&T Research (http://www.graphviz.org/)
    I used it to generate postscript and GIF renderings.

[2] VCG is an interactive tool originally for Visualising Compiler Graphs.

    Can also generate hardcopy, but I find it most useful for
    interactive visualisation.
