Graph-ReadWrite 1.02 This is a collection of perl classes for reading and writing directed graphs in a variety of file formats. There are two base classes: Graph::Reader Base class for classes which read a graph file and create an instance of the Graph class. Graph::Writer Base class for classes which take an instance of the Graph class and write it out in a specific file format. This distribution also defines a simple XML format for storing directed graphs, defined to meet the needs of the Graph class. A reader and writer are provided for this: Graph::Reader::XML Graph::Writer::XML Writers are also included for Dot, VCG, and daVinci, two packages for displaying / rendering graphs. Dot and VCG are freely available; daVinci is freely available at the moment, but that is going to change soon. Graph::Writer::Dot Graph::Writer::VCG Graph::Writer::daVinci Dependencies: Graph Jarkko's Graph classes XML::Parser if you use Graph::Reader::XML XML::Writer if you use Graph::Writer::XML IO::File Bugs, suggestions, and new readers and writers will be gratefully received.
