METHODS
new
loc
my $label = $graph -> label(…);
$label->loc('t'); # put label to top of graph
For graphs and clusters, only "t"
(top)and "b"
(bottom, default) are allowed.
Possible values for nodes seem to be "t"
, "b"
and "c"
(centered, default). The value is only used when the height of the node is larger than the height of its label.
