Grid Drawings and the Chromatic Number
A grid drawing of a graph maps vertices to the grid ℤ d and edges to line segments that avoid grid points representing other vertices. We show that a graph G is q ...

Drawing Graphs Using a Small Number of Obstacles
An obstacle representation of a graph G is a set of points in the plane representing the vertices of G, together with a set of polygonal obstacles such that two vertices of G are connected by an edge in G if and ...

Minimal Representations of Order Types by Geometric Graphs
In order to have a compact visualization of the order type of a given point set S, we are interested in geometric graphs on S with few edges that unequivocally display the order type of S. We introduce the concep...
