Center node: "drawing trees with perfect angular resolution and polynomial area"
  Abstract: We study methods for drawing trees with perfect angular resolution, i.e., with angles at each node $$v$$ equal to $$2\pi /d(v)$$. We show:1.Any unordered tree has a crossing-free straight-line drawing with perfect angular resolution and polynomial area.2.There are ordered trees that require exponential area for any crossing-free straight-line drawing having perfect angular resolution.3.Any ordered tree has a crossing-free Lombardi-style drawing (where each edge is represented by a circular arc) with perfect angular resolution and polynomial area. Thus, our results explore what is achievable with straight-line drawings and what more is achievable with Lombardi-style drawings, with respect to drawings of trees with perfect angular resolution.
