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.



Constructor - generate a new writer instance.

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

This doesn't take any arguments.


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.
