Further Information

It is important to minimize the area of a drawing of a graph, so that the drawing can fit in a small drawing-space. It is well-known that a planar graph with n vertices admits a planar straight-line grid drawing with O(n2) area [H. de Fraysseix, J. Pach, R. Pollack, How to draw a planar graph on a grid, Combinatorica 10(1) (1990) 41-51; W. Schnyder. Embedding planar graphs on the grid, in: Proceedings of the First ACM-SIAM Symposium on Discrete Algorithms, 1990, pp. 138-148]. Unfortunately, there is a matching lower-bound of Ω(n2) on the area-requirements of the planar straight-line grid drawings of certain planar graphs. Hence, it is important to investigate important categories of planar graphs to determine if they admit planar straight-line grid drawings with o(n2) area. In this paper, we investigate an important category of planar graphs, namely, outerplanar graphs. We show that an outerplanar graph G with degree d admits a planar straight-line grid drawing with area O(dn1.48 ) in O(n) time. This implies that if d= o(n0.52), then G can be drawn in this manner in o(n2) area.
