  $wr->write_graph($g,'/tmp/graph.simple.dot');
  my $wr_png = Graph::Writer::GraphViz->new(-format => 'png');
  $wr_png->write_graph($g,'/tmp/graph.simple.png');
  Graph::Writer::GraphViz->new(
        -format => 'png',
        -layout => 'twopi',

        -fontsize => 8

Overview

Graph::Writer::GraphViz is a class for writing out a Graph object with GraphViz module. All GraphViz formats should be supported without a problem.

Methods

new()

Unlike other Graph::Writer modules, this module provide an extra parameter '-format' to new() method, in order to save different format. Other supported GraphViz parameters are -layout, -ranksep, -shape, -fontsize, -arrowsize. Please see the SYNOPSIS for example usage.

Valid format depends on those GraphViz as_fmt methods on your system, like, 'gif' if you have 'as_gif', 'text' if you can do 'as_text'.
