Standard graph API?

[Magnus Lie Hetland]

Is there any interest in a (hypothetical) standard graph API (with
'graph' meaning a network, consisting of nodes and edges)? Yes, we
have the standard ways of implementing graphs through (e.g.) dicts
mapping nodes to neighbor-sets, but if one wants a graph that's
implemented in some other way, this may not be the most convenient (or
abstract) interface to emulate. It might be nice to have the kind of
polymorphic freedom that one has with, e.g, with the DB-API. One could
always develop factories or adaptors (such as for PyProtocols) to/from
the dict-of-sets version...

So, any interest? Or am I just a lone nut in wanting this?
