Rectangle-visibility representations of bipartite graphs,rizontal and vertical visibility. It is shown that, for .. has a representation with no rectangles having collinear sides if and only if .≤3 or .=3 and .≤4. More generally, it is shown that .. is a rectangle-visibility graph if and only if .≤4. Finally, it is shown that every bipartite rectangle-vis

Directed VR-representable graphs have unbounded dimension,ensional visibility representation that has been studied is one in which each vertex of the graph maps to a closed rectangle in ℝ. and edges are expressed by vertical visibility between rectangles. The rectangles representing vertices are disjoint, contained in planes perpendicular to the .-axis, an

https://doi.org/10.1007/978-981-19-9342-8The model of the torus as a parallelogram in the plane with opposite sides identified enables us to speak of upward drawings of graphs in the torus. It is shown that upward embeddings of a toroidal map can be obtained in a very natural way by means of flow techniques.

Ahmed Idris Hassen,F. L. Bopape,L. K. SangerAn . is a graph with a fixed cyclic order of edges around each vertex and an angle specified for every pair of consecutive edges incident on each vertex. We study the problem of constructing a drawing of an angle graph that preserves its angles, and present several new results.
