In a previous paper, the authors reduced the characterization of visibility graphs of simple polygons to the coordinatization of certain uniform rank 3 oriented matroids. We show here that in the case of 2-spiral polygons such coordinatization is possible therefore characterizing visibility graphs of 2-spiral polygons.
