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'.
