NAME ^

Graph::Writer::GraphViz - GraphViz Writer for Graph object

SYNOPSIS ^

  my @v = qw/Alice Bob Crude Dr/;
  my $g = Graph->new(@v);

  my $wr = Graph::Writer::GraphViz->new(-format => 'dot');
  $wr->write_graph($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',
        -ranksep => 1.5,
        -fontsize => 8
        -edge_color => 'grey',
        -node_color => 'black',
       )->write_graph($g,'/tmp/graph.png');

DESCRIPTION ^

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'.

SEE ALSO ^
