As an uninterpreted first order language of a binary relation, the language
of set theory is "about arbitrary oriented graphs". Is there an easy way to
select, among them, "graphs of sets"? And, are "graphs of sets" the only
possible kind of oriented graphs allowing to express the entire mathematics?
