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'.
