Graph::Writer::Dot - write out directed graph in Dot format
use Graph; use Graph::Writer::Dot; $graph = Graph->new(); # add edges and nodes to the graph $writer = Graph::Writer::Dot->new(); $writer->write_graph($graph, 'mygraph.dot');
Graph::Writer::Dot is a class for writing out a directed graph in the file format used by the dot tool (part of the AT+T graphviz package). The graph must be an instance of the Graph class, which is actually a set of classes developed by Jarkko Hietaniemi.

$writer = Graph::Writer::Dot->new();
This doesn't take any arguments.
Write a specific graph to a named file:
$file argument can either be a filename, or a filehandle for a previously opened file.
