In a recent paper, Frisch, Kechris, Shinko, and Vidnyánszky proved many results about topological realizations of countable Borel equivalence relations (CBERs). We discuss some of their results about compactly graphable CBERs and make partial progress toward the question of whether every aperiodic CBER has a compactly graphable realization.
