NAME

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

SYNOPSIS

	 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');

DESCRIPTION

       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.

METHODS

   new()
       Constructor - generate a new writer instance.

	 $writer = Graph::Writer::Dot->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.
