Resolving Conflicting Insights in Asynchronous Collaborative Visual Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Analyzing large and complex datasets for critical decision making can benefit from a collective effort involving a team of analysts. However, insights and findings from different analysts are often incomplete, disconnected, ... -
Data Comets: Designing a Visualization Tool for Analyzing Autonomous Aerial Vehicle Logs with Grounded Evaluation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Autonomous unmanned aerial vehicles are complex systems of hardware, software, and human input. Understanding this complexity is key to their development and operation. Information visualizations already exist for exploring ... -
GTMapLens: Interactive Lens for Geo-Text Data Browsing on Map
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Data containing geospatial semantics, such as geotagged tweets, travel blogs, and crime reports, associates natural language texts with geographical locations. This paper presents a lens-based visual interaction technique, ... -
LOCALIS: Locally-adaptive Line Simplification for GPU-based Geographic Vector Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Visualization of large vector line data is a core task in geographic and cartographic systems. Vector maps are often displayed at different cartographic generalization levels, traditionally by using several discrete ... -
Feature Driven Combination of Animated Vector Field Visualizations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Animated visualizations are one of the methods for finding and understanding complex structures of time-dependent vector fields. Many visualization designs can be used to this end, such as streamlines, vector glyphs, and ... -
A Globally Conforming Lattice Structure for 2D Stress Tensor Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a visualization technique for 2D stress tensor fields based on the construction of a globally conforming lattice. Conformity ensures that the lattice edges follow the principal stress directions and the aspect ... -
PAVED: Pareto Front Visualization for Engineering Design
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Design problems in engineering typically involve a large solution space and several potentially conflicting criteria. Selecting a compromise solution is often supported by optimization algorithms that compute hundreds of ... -
Set Streams: Visual Exploration of Dynamic Overlapping Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In many applications, membership of set elements changes over time. Since each element can be present in multiple sets, the sets also overlap. As a result, it becomes challenging to visualize the temporal change in set ... -
Quantitative Comparison of Time-Dependent Treemaps
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Rectangular treemaps are often the method of choice to visualize large hierarchical datasets. Nowadays such datasets are available over time, hence there is a need for (a) treemaps that can handle time-dependent data, and ... -
Augmenting Node-Link Diagrams with Topographic Attribute Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose a novel visualization technique for graphs that are attributed with scalar data. In many scenarios, these attributes (e.g., birth date in a family network) provide ambient context information for the graph ... -
Metro Maps on Octilinear Grid Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Schematic transit maps (often called "metro maps" in the literature) are important to produce comprehensible visualizations of complex public transit networks. In this work, we investigate the problem of automatically ... -
Fuzzy Contour Trees: Alignment and Joint Layout of Multiple Contour Trees
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We describe a novel technique for the simultaneous visualization of multiple scalar fields, e.g. representing the members of an ensemble, based on their contour trees. Using tree alignments, a graph-theoretic concept similar ... -
Visual Analysis of the Finite-Time Lyapunov Exponent
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In this paper, we present an integrated visual analytics approach to support the parametrization and exploration of flow visualization based on the finite-time Lyapunov exponent. Such visualization of time-dependent flow ... -
Fiber Surfaces for many Variables
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Scientific visualization deals with increasingly complex data consisting of multiple fields. Typical disciplines generating multivariate data are fluid dynamics, structural mechanics, geology, bioengineering, and climate ... -
Extraction of Distinguished Hyperbolic Trajectories for 2D Time-Dependent Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper does two main contributions to 2D time-dependent vector field topology. First, we present a technique for robust, accurate, and efficient extraction of distinguished hyperbolic trajectories (DHT), the generative ... -
Co-creating Visualizations: A First Evaluation with Social Science Researchers
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Co-creation is a design method where designers and domain experts work together to develop a product. In this paper, we present and evaluate the use of co-creation to design a visual information system with social science ... -
Structure and Empathy in Visual Data Storytelling: Evaluating their Influence on Attitude
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In the visualization community, it is often assumed that visual data storytelling increases memorability and engagement, making it more effective at communicating information. However, many assumptions about the efficacy ... -
Short-Contact Touch-Manipulation of Scatterplot Matrices on Wall Displays
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper presents a short-contact multitouch vocabulary for interacting with scatterplot matrices (SPLOMs) on wall-sized displays. Fling-based gestures overcome central interaction challenges of such large displays by ... -
Phase Space Projection of Dynamical Systems
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Dynamical systems are commonly used to describe the state of time-dependent systems. In many engineering and control problems, the state space is high-dimensional making it difficult to analyze and visualize the behavior ... -
