GraphViz::Small - subclass of GraphViz with small nodes

SYNOPSIS

Top

  use GraphViz::Small;

  my $g = GraphViz::Small->new();
  # methods as for GraphViz

DESCRIPTION

Graphs produced by GraphViz are occasionally huge, making it hard to observe the structure. This subclass simply makes the nodes small and empty, allowing the structure to stand out.

METHODS
