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, Hash::FieldHash has been used to
|
|
provide getters and setters, rather than Moose.
