โฆ Synopsis
In this paper we introduce a new drawing style of a plane graph G called a box-rectangular drawing. It is defined to be a drawing of G on an integer grid such that every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal line segment or a vertical line segment, and the contour of each face is drawn as a rectangle. We establish a necessary and sufficient condition for the existence of a box-rectangular drawing of G. We also give a linear-time algorithm to find a box-rectangular drawing of G if it exists.

We consider graphs drawn in the plane such that every edge crosses at most one other edge. We characterize, in terms of two forbidden subconfigurations, which of these graphs are equivalent to drawings such that all edges are straight line segments. As a consequence we obtain a complete characteriza
## Abstract Let __G__ be a graph drawn in the plane so that its edges are represented by __x__โmonotone curves, any pair of which cross an even number of times. We show that __G__ can be redrawn in such a way that the __x__โcoordinates of the vertices remain unchanged and the edges become nonโcross
## Abstract A plane graph __G__ is coupled __k__โchoosable if, for any list assignment __L__ satisfying $|{{L}}({{x}})|= {{k}}$ for every ${{x}}\in {{V}}({{G}})\cup {{F}}({{G}})$, there is a coloring that assigns to each vertex and each face a color from its list such that any two adjacent or incid
Map the vertices of a graph to (not necessarily distinct) points of the plane so that two adjacent vertices are mapped at least unit distance apart. The plane-width of a graph is the minimum diameter of the image of its vertex set over all such mappings. We establish a relation between the plane-wid
