We study how much better a right-angled crossing (RAC) drawing of a planar graph can be than any planar drawing of the same planar graph. We analyze the area requirement, the edge-length ratio, and the angular resolution. For the first two measures, a RAC drawing can be arbitrarily much better, whereas for the third measure a RAC drawing can be 2.75 times as good.
Van Kreveld REF studied how much better (in terms of area required, edge-length and angular resolution) a RAC drawing of a planar graph can be than any planar drawing of the same graph.
