A simple linear time algorithm for proper box rectangular drawings of plane graphs

Abstract

In this paper we introduce a new drawing style of a plane graph G, called proper box rectangular (PBR) drawing. It is defined to be a drawing of G such that every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal or a vertical line segment, and each face is drawn as a rectangle. We establish necessary and sufficient conditions for G to have a PBR drawing. We also give a simple linear time algorithm for finding such drawings. The PBR drawing is closely related to the box rectangular (BR) drawing defined by Rahman, Nakano and Nishizeki [17]. Our method can be adapted to provide a new algorithm for solving the BR drawing problem.
