Abstract:We consider orthogonal drawings of a plane graph GG with specified face areas. For a natural number kk, a kk-gonal drawing of GG is an orthogonal drawing such that the boundary of GG is drawn as a rectangle and each inner face is drawn as a polygon with at most kk corners whose area is equal to the specified value. In this paper, we show that every slicing graph GG with a slicing tree TT and a set of specified face areas admits a 10-gonal drawing DD such that the boundary of each slicing subgraph that appears in TT is also drawn as a polygon with at most 10 corners. Such a drawing DD can be found in linear time.
Keywords:Graph algorithms  Graph drawing  Orthogonal drawing  Plane graphs  Slicing graphs
