Rectangular Drawings of Plane Graphs Without Designated Corners
A rectangular drawing of a plane graph G is a drawing of G such that each vertex is drawn as a point, each edge is drawn as a horizontal or a vertical line segment, and the contour of each face is drawn as a rectangle. A necessary and sufficient condition for the existence of a rectangular drawing has been known only for the case where exactly four vertices of degree 2 are designated as corners...
متن کاملExtended Rectangular Drawings of Plane Graphs with Designated Corners
In a rectangular drawing of a plane graph, each edge is drawn as a horizontal or vertical line segment, and all faces including the outer face are drawn as rectangles. In this paper, we introduce an “extended rectangular drawing” in which all inner faces are drawn as rectangles but the outer face is drawn as a rectilinear polygon with designated corners, and give a necessary and sufficient cond...
متن کاملRectangular Grid Drawings of Plane Graphs
The rectangular grid drawing of a plane graph G is a drawing of G such that each vertex is located on a grid point, each edge is drawn as a horizontal or vertical line segment, and the contour of each face is drawn as a rectangle. In this paper we give a simple linear-time algorithm to find a rectangular grid drawing of G if it exists. We also give an upper bound W + H <~ n /2 on the sum of req...
متن کاملInner Rectangular Drawings of Plane Graphs
A drawing of a plane graph is called an inner rectangular drawing if every edge is drawn as a horizontal or vertical line segment so that every inner face is a rectangle. In this paper we show that a plane graph G has an inner rectangular drawing D if and only if a new bipartite graph constructed from G has a perfect matching. We also show that D can be found in time O(n/ logn) if G has n verti...
متن کاملBox-Rectangular Drawings of Plane Graphs
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 cond...
