Recently I ported Wikipedia information about members of 18th century Scottish clubs and societies into wikidata with a view to using SPARQL to visualise Enlightenment networks, as shown here. As ever, it could be expanded (e.g. Speculative Society), but for the moment I think this is quite a pleasing view, which can be clicked to see individuals' interests. Link I did also generate an equivalent diagram for 19th century literary societies (Maitland Club, Bannatyne Club, Society of Antiquaries, etc.) - which was actually my starting point for this whole thing - but the diagram resembles a bowl of broth: it's all in there but too many little pieces to be usable.
