On the Perception of Small Sub-graphs
Jacob Miller, Mohammad Ghoniem, Hsiang-Yun Wu +1
Interpreting a node-link graph is enhanced if similar subgraphs (or motifs) are depicted in a similar manner; that is, they have the same visual form. Small motifs within graphs ma…
Shape-Guided Mixed Metro Map Layout
Tobias Batik, Soeren Terziadis, Yu-Shuen Wang +2
Metro or transit maps, are schematic representations of transit networks to facilitate effective route-finding. These maps are often advertised on a web page or pamphlet highlighti…
A Survey on Computing Schematic Network Maps: The Challenge to Interactivity
Hsiang-Yun Wu, Benjamin Niedermann, Shigeo Takahashi +1
Schematic maps are in daily use to show the connectivity of subway systems and to facilitate travellers to plan their journeys effectively. This study surveys up-to-date algorithmi…
Nested Papercrafts for Anatomical and Biological Edutainment
Marwin Schindler, Thorsten Korpitsch, Renata G. Raidou +1
In this paper, we present a new workflow for the computer-aided generation of physicalizations, addressing nested configurations in anatomical and biological structures. Physicaliz…
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…
Untangling Circular Drawings: Algorithms and Complexity
Sujoy Bhore, Guangping Li, Martin Nöllenburg +2
We consider the problem of untangling a given (non-planar) straight-line circular drawing of an outerplanar graph into a planar straight-line circular drawing by s…
Graph Models for Biological Pathway Visualization: State of the Art and Future Challenges
Hsiang-Yun Wu, Martin Nöllenburg, Ivan Viola
The concept of multilayer networks has become recently integrated into complex systems modeling since it encapsulates a very general concept of complex relationships. Biological pa…
Context-Responsive Labeling in Augmented Reality
Thomas Köppel, M. Eduard Gröller, Hsiang-Yun Wu
Route planning and navigation are common tasks that often require additional information on points of interest. Augmented Reality (AR) enables mobile users to utilize text labels,…
The Future is Big Graphs! A Community View on Graph Processing Systems
Sherif Sakr, Angela Bonifati, Hannes Voigt +38
Graphs are by nature unifying abstractions that can leverage interconnectedness to represent, explore, predict, and explain real- and digital-world phenomena. Although real users a…
Slice and Dice: A Physicalization Workflow for Anatomical Edutainment
Renata G. Raidou, M. Eduard Gröller, Hsiang-Yun Wu
During the last decades, anatomy has become an interesting topic in education---even for laymen or schoolchildren. As medical imaging techniques become increasingly sophisticated,…
The Anatomical Edutainer
Marwin Schindler, Hsiang-Yun Wu, Renata Georgia Raidou
Physical visualizations (i.e., data representations by means of physical objects) have been used for many centuries in medical and anatomical education. Recently, 3D printing techn…
The Turing Test for Graph Drawing Algorithms
Helen C. Purchase, Daniel Archambault, Stephen Kobourov +3
Do algorithms for drawing graphs pass the Turing Test? That is, are their outputs indistinguishable from graphs drawn by humans? We address this question through a human-centred ex…
Exploring the Limits of Complexity: A Survey of Empirical Studies on Graph Visualisation
Vahan Yoghourdjian, Daniel Archambault, Stephan Diehl +4
For decades, researchers in information visualisation and graph drawing have focused on developing techniques for the layout and display of very large and complex networks. Experim…
Optical polarization variations in the blazar PKS 1749+096
Makoto Uemura, Ryosuke Itoh, Ioannis Liodakis +6
We report on the variation in the optical polarization of the blazar PKS 1749+096 observed in 2008--2015. The degree of polarization (PD) tends to increase in short flares having a…
