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 ... -
CPU Ray Tracing of Tree-Based Adaptive Mesh Refinement Data
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Adaptive mesh refinement (AMR) techniques allow for representing a simulation's computation domain in an adaptive fashion. Although these techniques have found widespread adoption in high-performance computing simulations, ... -
SeqDynamics: Visual Analytics for Evaluating Online Problem-solving Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Problem-solving dynamics refers to the process of solving a series of problems over time, from which a student's cognitive skills and non-cognitive traits and behaviors can be inferred. For example, we can derive a student's ... -
Bombalytics: Visualization of Competition and Collaboration Strategies of Players in a Bomb Laying Game
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Competition and collaboration form complex interaction patterns between the agents and objects involved. Only by understanding these interaction patterns, we can reveal the strategies the participating parties applied. In ... -
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 ... -
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 ... -
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 ... -
WarehouseVis: A Visual Analytics Approach to Facilitating Warehouse Location Selection for Business Districts
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Selecting a proper warehouse location serving to satisfy the demands of the goods from a certain business area is important to a successful retail business. However, the large solution space, uncertain traffic conditions, ... -
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, ... -
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 ... -
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 ... -
Orchard: Exploring Multivariate Heterogeneous Networks on Mobile Phones
(The Eurographics Association and John Wiley & Sons Ltd., 2020)People are becoming increasingly sophisticated in their ability to navigate information spaces using search, hyperlinks, and visualization. But, mobile phones preclude the use of multiple coordinated views that have proven ... -
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 ... -
Sunspot Plots: Model-based Structure Enhancement for Dense Scatter Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Scatter plots are a powerful and well-established technique for visualizing the relationships between two variables as a collection of discrete points. However, especially when dealing with large and dense data, scatter ... -
VisuaLint: Sketchy In Situ Annotations of Chart Construction Errors
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Chart construction errors, such as truncated axes or inexpressive visual encodings, can hinder reading a visualization, or worse, imply misleading facts about the underlying data. These errors can be caught by critical ... -
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, ... -
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 ... -
Representative Isovalue Detection and Isosurface Segmentation Using Novel Isosurface Measures
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Interval volume is the volume of the region between two isosurfaces. This paper proposes a novel measure, called VOA measure, that is computed based on interval volume and isosurface area. This measure represents the rate ... -
QUESTO: Interactive Construction of Objective Functions for Classification Tasks
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Building effective classifiers requires providing the modeling algorithms with information about the training data and modeling goals in order to create a model that makes proper tradeoffs. Machine learning algorithms allow ... -
