NAME
   Soar::WM::Grapher - Utility for creating graphs of Soar's working memory

VERSION
   version 0.02

SYNOPSIS
     use Soar::WM;
     use Soar::WM::Grapher qw(wm_graph);
     my $wm = Soar::WM->new(file=>'path/to/wme/dump');
     my $wme_id = 'S1'; #name of WME to begin graph from
     my $depth = 2; #number of levels to traverse during graphing
     my $g = wm_graph($wm, $wme_id, $depth, layout => 'twopi', ratio => 'compress', overlap=>'scale');
     $g->as_svg('wm_graph.svg');

DESCRIPTION
   This module can be used to create GraphViz representations of Soar
   working memory.

NAME
   Soar::WM - Perl extension for representing Soar working memory given a
   WME dump file

METHODS
 "wm_graph"
   There are three required arguments: a Soar::WM object, the ID of the
   working memory element to begin graphing from, and the depth to graph.
   If the depth is 1, then only the specified element and its
   attribute-value pairs will be graphed. 2 will also graph each of the
   WMEs attached to the first node, and so on. The return value is a
   GraphViz object. Any extra arguments passed to this function are passed
   on to the GraphViz constructor; therefore, you can specify graphing
   options such as layout, as seen in the synopsis above.

TODO
   I understand that GraphViz is deprecated in favor of GraphViz2. However,
   I cannot cleanly install GraphViz2 on my own computer (it has a rather
   large dependency list). When I can cleanly install GraphViz2, I'll
   switch to that module.

SEE ALSO
   The "wm_graph" function accepts many optional arguments specified by the
   GraphViz module.
