Jul 10, 2019 at 20:07 comment added Jan Kyncl Is the question asking about universal sets for 1-plane drawings of planar graphs?
Nov 10, 2018 at 12:16 comment added Joseph O'Rourke 1-planar graphs have a drawing---not necessarily with straight edges---where each edge is crossed by at most one other edge. I'm using "1-plane graphs" to also require straight edges.
