Yes, this is essentially the same.  My example above just shows the
pattern that needs to be used.  Roel’s module there exports *all* the
procedures.

The point, however, is — as Dmitry wrote earlier — that gv does not
provide any predicates or search algorithms.  gv only provides
constructors and accessors to the graphviz data structure, and the means
to render them.
