Lower Bounds for Local Monotonicity Reconstruction from Transitive-Closure Spanners
Abstract. Given a directed graph G = (V, E) and an integer k 1, a ktransitive-closure-spanner (k-TC-spanner) of G is a directed graph H = (V, EH ) that has (1) the same transitive...

Generalizing the Shift Method for Rectangular Shaped Vertices with Visibility Constraints
In this paper we present a generalization of the shift method algorithm [4, 6] to obtain a straight-line grid drawing of a triconnected graph, where vertex representations have a c...

The Dominance Tree in Visualizing Software Dependencies
Dominance analysis from graph theory allows one to locate subordinated software elements in a rooted dependency graph. It identifies the nesting structure for a dependency graph ...

Track Layouts of Graphs
A (k, t)-track layout of a graph G consists of a (proper) vertex t-colouring of G, a total order of each vertex colour class, and a (non-proper) edge k-colouring such that between...

Sphere Anchored Map: A Visualization Technique for Bipartite Graphs in 3D
Circular anchored maps have been proposed as a drawing technique to acquire knowledge from bipartite graphs, where nodes in one set are arranged on a circumference. However, the re...
