Tangling and Untangling Trees on Point-sets
Giuseppe Di Battista, Giuseppe Liotta, Maurizio Patrignani +2
We study a question that lies at the intersection of classical research subjects in Topological Graph Theory and Graph Drawing: Computing a drawing of a graph with a prescribed num…
Planar Stories of Graph Drawings: Algorithms and Experiments
Carla Binucci, Sabine Cornelsen, Walter Didimo +5
We address the problem of computing a dynamic visualization of a geometric graph as a sequence of frames. Each frame shows only a portion of the graph but their union covers $G…
Optimal Orthogonal Drawings in Linear Time
Walter Didimo, Giuseppe Liotta, Giacomo Ortali +1
A planar orthogonal drawing Γ of a connected planar graph G is a geometric representation of G such that the vertices are drawn as distinct points of the plane, the edges are drawn…
Simple Realizability of Abstract Topological Graphs
Giordano Da Lozzo, Walter Didimo, Fabrizio Montecchiani +3
An abstract topological graph (AT-graph) is a pair , where is a graph and is a set of pairs of edges of . A re…
The Price of Upwardness
Patrizio Angelini, Therese Biedl, Markus Chimani +8
Not every directed acyclic graph (DAG) whose underlying undirected graph is planar admits an upward planar drawing. We are interested in pushing the notion of upward drawings beyon…
