SYNOPSIS
        use Graph::Easy;
        my $graph = Graph::Easy->new();
        my $bonn = Graph::Easy::Node->new(
                name => 'Bonn',
        );
        my $berlin = Graph::Easy::Node->new(
                name => 'Berlin',
        );
        $graph->add_edge ($bonn, $berlin);
        print $graph->as_vcg();
This prints something like this:
        graph: {
                node: { title: "Bonn" }
                node: { title: "Berlin" }
                edge: { sourcename: "Bonn" targetname: "Berlin" }
        }
DESCRIPTION
"Graph::Easy::As_vcg" contains just the code for converting a Graph::Easy object to either a VCG or GDL textual description.Note that the generated format is compatible to "GDL" aka Graph Description Language.
