Does there exist a set of intervals, no 5 of which share a point, such that the interval graph (this is the graph formed by taking the vertices to be the intervals, and then you connect two of the vertices by an edge if the corresponding intervals intersect) is non-planar? Prove or disprove. Please do not just give the definition of interval graphs as others have for this same question.
