=head1 NAME
GraphViz::No - subclass of GraphViz with no nodes
=head1 SYNOPSIS
use GraphViz::No;
my $g = GraphViz::No->new();
# methods as for GraphViz
=head1 DESCRIPTION
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.
=head1 METHODS
As for GraphViz.
