The base system (GraphViz) allows you to specify multiple label to a nodes and apparently also specify the compass point to 'place the label' at a particular point on the node based on the points of a compass. ie. 

a -> b:f0:se

'connect node 'a' to node 'b' at label 'f0' at the compass point 'se' (south east).

But the perl interface doesn't mention how to specify this option. It only talks about assigning 'multiple labels' to a node and how to select a connection to a specific node.

Tomorrow I might try: 

$g->add_node('a');
$g->add_node('b', label => ['0', '1']);
$g->add_edge('a' => 'b', to_port => '0:se');

Comments anyone?
