Wrapper for AT&T Graphviz

This module provides a Perl interface to the amazing Graphviz, an open source graph visualization tool from AT&T.

It is called GraphViz2 so that pre-existing code using the Perl module GraphViz continues to work.

To avoid confusion, when I use GraphViz2 note the capital V, I’m referring to this Perl module, and when I use Graphviz lower-case v I’m referring to the underlying tool which is in fact a set of programs.

This version of GraphViz2 targets Graphviz 2.23.6+.

GraphViz2 1.x is a complete re-write, by Ron Savage, of GraphViz 2.x, which was written by Leon Brocard. The point of the re-write is to provide access to all the latest options available to users of Graphviz.

GraphViz2 1.x is not backwards compatible with GraphViz 2.x, despite the considerable similarity. It was not possible to maintain compatibility while extending support to all the latest features of Graphviz.

To ensure GraphViz2 is a light-weight module, HashFieldHash has been used to provide getters and setters, rather than Moose.
