Convex Grid Drawings of 3-Connected Planar Graphs
Marek Chrobák, Goos Kant · International Journal of Computational Geometry & Applications · 1997
We consider the problem of embedding the vertices of a plane graph into a small (polynomial size) grid in the plane in such a way that the edges are straight, nonintersecting line segments and faces are convex polygons. We present a linear-time algorithm which, given an n-vertex 3-connected plane G (with n ≥ 3), finds such a straight-line convex embedding of G into a (n - 2) × (n - 2) grid.
