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.
