Automated Responsive Thematic Mapping with Layout Guides
Arjen Simons, Sarah Schöttler, Wouter Meulemans +2
Thematic maps visually communicate statistical information about spatial units such as countries or states. They must balance the individual readability of those map elements that…
BlockSets: A Structured Visualization for Sets with Large Elements
Neda Novakova, Veselin Todorov, Steven van den Broek +2
Visualizations of set systems frequently use enclosing geometries for the sets in combination with reduced representations of the elements, such as short text labels, small glyphs,…
Summarizing Classed Region Maps with a Disk Choreme
Steven van den Broek, Wouter Meulemans, Andreas Reimer +1
Chorematic diagrams are highly reduced schematic maps of geospatial data and processes. They can visually summarize complex situations using only a few simple shapes (choremes) pla…
Bounds for k-centers of point sets under -bottleneck distance
Mats Bierwirth, Julia Hütte, Patrick Schnider +1
We consider the -center problem on the space of fixed-size point sets in the plane under the -bottleneck distance. While this problem is motivated by persistence dia…
SimpleSets: Capturing Categorical Point Patterns with Simple Shapes
Steven van den Broek, Wouter Meulemans, Bettina Speckmann
Points of interest on a map such as restaurants, hotels, or subway stations, give rise to categorical point data: data that have a fixed location and one or more categorical attrib…
Greedy Monochromatic Island Partitions
Steven van den Broek, Wouter Meulemans, Bettina Speckmann
Constructing partitions of colored points is a well-studied problem in discrete and computational geometry. We study the problem of creating a minimum-cardinality partition into mo…
Capturing the Shape of a Point Set with a Line Segment
Nathan van Beusekom, Marc van Kreveld, Max van Mulken +3
Detecting location-correlated groups in point sets is an important task in a wide variety of applications areas. In addition to merely detecting such groups, the group's shape carr…
Optimizing Symbol Visibility through Displacement
Bernd Gärtner, Vishwas Kalani, Meghana M. Reddy +3
In information visualization, the position of symbols often encodes associated data values. When visualizing data elements with both a numerical and a categorical dimension, positi…
