Paged Geophylogenies: A Coloring Approach to External Labeling with Tree Constraints
Thomas Depian, Thomas C. van Dijk, Martin Nöllenburg
Geophylogenies are a common type of diagram for visualizing the evolutionary history of species in a geographic context. As a drawing problem, these diagrams are commonly modeled a…
Visualizing Geophylogenies -- Internal and External Labeling with Phylogenetic Tree Constraints
Jonathan Klawitter, Felix Klesen, Joris Y. Scholl +2
A geophylogeny is a phylogenetic tree (or dendrogram) where each leaf (e.g. biological taxon) has an associated geographic location (site). To clearly visualize a geophylogeny, the…
Bundled Crossings Revisited
Steven Chaplick, Thomas C. van Dijk, Myroslav Kryven +3
An effective way to reduce clutter in a graph drawing that has (many) crossings is to group edges that travel in parallel into \emph{bundles}. Each edge can participate in many suc…
Block Crossings in Storyline Visualizations
Thomas C. van Dijk, Martin Fink, Norbert Fischer +5
Storyline visualizations help visualize encounters of the characters in a story over time. Each character is represented by an x-monotone curve that goes from left to right. A meet…
Snapping Graph Drawings to the Grid Optimally
Andre Löffler, Thomas C. van Dijk, Alexander Wolff
In geographic information systems and in the production of digital maps for small devices with restricted computational resources one often wants to round coordinates to a rougher…
Improved Approximation Algorithms for Box Contact Representations
Michael A. Bekos, Thomas C. van Dijk, Martin Fink +5
We study the following geometric representation problem: Given a graph whose vertices correspond to axis-aligned rectangles with fixed dimensions, arrange the rectangles without ov…
