GraphViz::No - subclass of GraphViz with no nodes
use GraphViz::No; my $g = GraphViz::No->new(); # methods as for GraphViz
Graphs produced by GraphViz are occasionally huge, making it hard to observe the structure. This subclass removes the nodes, so that only the edges are visible. This allows the structure to stand out.
As for GraphViz.
