This has an implication of inability to cache results in case you might want
it. I personally would just leave empty #+RESULTS: block as is and I would
place link manually two lines below it (leave 1 blank line so re-evaluation
won't delete your link).

I never used that library but it makes sense:-) The only problem with this
solution that you should make sure nothing else goes to stdout. I think it
is a huge shortcoming.

As William LECHELLE pointed out that in this case file captures the output
of the savefig() call which does not output anything to stdout. So it is
expected.

I think this is the best way to proceed.
