Center node: "outerplanar graph drawings with few slopes"
  Abstract: We consider straight-line outerplanar drawings of outerplanar graphs in which a small number of distinct edge slopes are used, that is, the segments representing edges are parallel to a small number of directions. We prove that @D-1 edge slopes suffice for every outerplanar graph with maximum degree @D>=4. This improves on the previous bound of O(@D^5), which was shown for planar partial 3-trees, a superclass of outerplanar graphs. The bound is tight: for every @D>=4 there is an outerplanar graph with maximum degree @D that requires at least @D-1 distinct edge slopes in an outerplanar straight-line drawing.
