On 1-bend Upward Point-set Embeddings of -digraphs

Emilio Di Giacomo, Henry Förster, Daria Kokhovich +4

We study the upward point-set embeddability of digraphs on one-sided convex point sets with at most 1 bend per edge. We provide an algorithm to compute a 1-bend upward point-set em…

MySemCloud: Semantic-aware Word Cloud Editing

Michael Huber, Martin Nöllenburg, Anaïs Villedieu

Word clouds are a popular text visualization technique that summarize an input text by displaying its most important words in a compact image. The traditional layout methods do not…

Crossing Minimization in Time Interval Storylines

Alexander Dobler, Martin Nöllenburg, Daniel Stojanovic +2

Storyline visualizations are a popular way of visualizing characters and their interactions over time: Characters are drawn as x-monotone curves and interactions are visualized thr…

Splitting Plane Graphs to Outerplanarity

Martin Gronemann, Martin Nöllenburg, Anaïs Villedieu

Vertex splitting replaces a vertex by two copies and partitions its incident edges amongst the copies. This problem has been studied as a graph editing operation to achieve desired…

Splitting Vertices in 2-Layer Graph Drawings

Reyan Ahmed, Patrizio Angelini, Michael A. Bekos +8

Bipartite graphs model the relationships between two disjoint sets of entities in several applications and are naturally drawn as 2-layer graph drawings. In such drawings, the two…

Minimum Link Fencing

Sujoy Bhore, Fabian Klute, Maarten Löffler +3

We study a variant of the geometric multicut problem, where we are given a set of colored and pairwise interior-disjoint polygons in the plane. The objective is to co…

Planarizing Graphs and their Drawings by Vertex Splitting

Martin Nöllenburg, Manuel Sorge, Soeren Terziadis +3

The splitting number of a graph is the minimum number of vertex splits required to turn into a planar graph, where a vertex split removes a vertex , introduc…

Multidimensional Manhattan Preferences

Jiehua Chen, Martin Nöllenburg, Sofia Simola +2

A preference profile (i.e., a collection of linear preference orders of the voters over a set of alternatives) with alternatives and voters is -Manhattan (resp. -Eucl…

Layered Area-Proportional Rectangle Contact Representations

Martin Nöllenburg, Anaïs Villedieu, Jules Wulms

We investigate two optimization problems on area-proportional rectangle contact representations for layered, embedded planar graphs. The vertices are represented as interior-disjoi…
