NAME

       Graph::Writer::daVinci - write out directed graph in daVinci format

SYNOPSIS

         use Graph;
         use Graph::Writer::daVinci;

         $graph = Graph->new();
         # add edges and nodes to the graph

         $writer = Graph::Writer::daVinci->new();
         $writer->write_graph($graph, 'mygraph.davinci');

DESCRIPTION

       Graph::Writer::daVinci is a class for writing out a directed graph in the file format used
       by the daVinci tool.  The graph must be an instance of the Graph class, which is actually
       a set of classes developed by Jarkko Hietaniemi.

METHODS

   new()
       Constructor - generate a new writer instance.

         $writer = Graph::Writer::daVinci->new();

       This doesn't take any arguments.

   write_graph()
       Write a specific graph to a named file:

         $writer->write_graph($graph, $file);

       The $file argument can either be a filename, or a filehandle for a previously opened file.
