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 ... -
DRLViz: Understanding Decisions and Memory in Deep Reinforcement Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present DRLViz, a visual analytics interface to interpret the internal memory of an agent (e.g. a robot) trained using deep reinforcement learning. This memory is composed of large temporal vectors updated when the agent ... -
EuroVis 2020 CGF 39-3: Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2020) -
Evaluating Reordering Strategies for Cluster Identification in Parallel Coordinates
(The Eurographics Association and John Wiley & Sons Ltd., 2020)The ability to perceive patterns in parallel coordinates plots (PCPs) is heavily influenced by the ordering of the dimensions. While the community has proposed over 30 automatic ordering strategies, we still lack empirical ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
Hairy Slices II: Depth Cues for Visualizing 3D Streamlines Through Cutting Planes
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Visualizing 3D vector fields is challenging because of occlusion problems and the difficulty of providing depth cues that adequately support the perception of direction of flow lines in 3D space. One of the depth cues that ... -
Infomages: Embedding Data into Thematic Images
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Recent studies have indicated that visually embellished charts such as infographics have the ability to engage viewers and positively affect memorability. Fueled by these findings, researchers have proposed a variety of ... -
Knowledge-Assisted Comparative Assessment of Breast Cancer using Dynamic Contrast-Enhanced Magnetic Resonance Imaging
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Breast perfusion data are dynamic medical image data that depict perfusion characteristics of the investigated tissue. These data consist of a series of static datasets that are acquired at different time points and ... -
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 ... -
Many At Once: Capturing Intentions to Create And Use Many Views At Once In Large Display Environments
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper describes results from an observational, exploratory study of visual data exploration in a large, multi-view, flexible canvas environment. Participants were provided with a set of data exploration sub-tasks ... -
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 ... -
MotionGlyphs: Visual Abstraction of Spatio-Temporal Networks in Collective Animal Behavior
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Domain experts for collective animal behavior analyze relationships between single animal movers and groups of animals over time and space to detect emergent group properties. A common way to interpret this type of data ... -
Ocupado: Visualizing Location-Based Counts Over Time Across Buildings
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Understanding how spaces in buildings are being used is vital for optimizing space utilization, for improving resource allocation, and for the design of new facilities. We present a multi-year design study that resulted ... -
