[tpm] graphviz

[Fulko Hew]

Does anyone have experience using (the perl interface) to graphviz?

the base system allows you to specify multiple label to nodes and
apparently specify the compass point to 'place the label'

but the perl interface doesn't mention how to specify this option.
It only talks about 'multiple labels'.

Is this question too terse?  Not if you've played with graphviz.

TIA
