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 ... -
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 ... -
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 ... -
PEAX: Interactive Visual Pattern Search in Sequential Data Using Unsupervised Deep Representation Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present PEAX, a novel feature-based technique for interactive visual pattern search in sequential data, like time series or data mapped to a genome sequence. Visually searching for patterns by similarity is often ... -
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 ... -
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 ... -
Quantitative Evaluation of Time-Dependent Multidimensional Projection Techniques
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Dimensionality reduction methods are an essential tool for multidimensional data analysis, and many interesting processes can be studied as time-dependent multivariate datasets. There are, however, few studies and proposals ... -
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 ... -
Reading Traces: Scalable Exploration in Elastic Visualizations of Cultural Heritage Data
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Through a design study, we develop an approach to data exploration that utilizes elastic visualizations designed to support varying degrees of detail and abstraction. Examining the notions of scalability and elasticity in ... -
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 ... -
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, ...
