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);

        $graph->layout();

        print $graph->as_ascii( );

        # prints:
