Comment:
Oh, I was under the impression that those base classes shouldn't be
instantiated, but that seems to be unfounded after reading the docs. Looks
good to me! Lines 855-856 of
`$SAGE_ROOT/devel/sage/sage/graphs/base/graph_backends.py` contains
another exception which seems like it should be a `LookupError` but I'm
not sure I understand why the current exception is imported from
!NetworkX. Maybe there is a good reason for it?
