Incidence graphs are a tool to keep track of how curves intersect each other in space. Given a collection of curves in projective space, I will explain how to make its incidence graph and discuss some interesting questions that arise. For example, starting with a graph G, can we construct a collection of curves that intersect so that their incidence graph is G? If so, what can we say about the kinds of curves that are needed? No previous experience with graphs, projective space, or algebraic curves needed.
