Graph::Easy::As_vcg - Generate VCG/GDL text from Graph::Easy object

	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" }
	}

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.

Exports nothing.
