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.
