That depends a good bit on what you want to say about your graphs. One way to think about this kind of question is: with whom will you want to _share_ information about your graphs? If you are just recording this for your own internal purposes and you can keep your assertions minimal (e.g. where a graph came from and a datestamp) it might be easiest to just use a few minted predicates of your own.
PROV-O: https://www.w3.org/TR/prov-o/#prov-o-at-a-glance is an example of a powerful but extremely general vocabulary for discussing provenance issues. There will be some overhead to using someone else's vocabulary, and that overhead is worth paying exactly to the extent that you need to share your assertions with other people. --- A.
