38       "Graph::Easy" namespace:
39
40   layout()
41               $graph->layout();
42
43       Layout the actual graph.
44
45   _assign_ranks()
46               $graph->_assign_ranks();
47
48       Used by "layout()" to assign each node a rank, so they can be sorted
49       and grouped on these.
50
51   _optimize_layout
52       Used by "layout()" to optimize the layout as a last step.
