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'.
