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'.
