Learning Contextualized User Preferences for Co-Adaptive Guidance in Mixed-Initiative Topic Model Refinement
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Mixed-initiative visual analytics systems support collaborative human-machine decision-making processes. However, many multiobjective optimization tasks, such as topic model refinement, are highly subjective and ... -
Leveraging Topological Events in Tracking Graphs for Understanding Particle Diffusion
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Single particle tracking (SPT) of fluorescent molecules provides significant insights into the diffusion and relative motion of tagged proteins and other structures of interest in biology. However, despite the latest ... -
Line Weaver: Importance-Driven Order Enhanced Rendering of Dense Line Charts
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Line charts are an effective and widely used technique for visualizing series of ordered two-dimensional data points. The relationship between consecutive points is indicated by connecting line segments, revealing potential ... -
Local Extraction of 3D Time-Dependent Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present an approach to local extraction of 3D time-dependent vector field topology. In this concept, Lagrangian coherent structures, which represent the separating manifolds in time-dependent transport, correspond to ... -
A Novel Approach for Exploring Annotated Data With Interactive Lenses
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We introduce a novel approach for assisting users in exploring 2D data representations with an interactive lens. Focus-andcontext exploration is supported by translating user actions to the joint adjustments in camera and ... -
Optimal Axes for Data Value Estimation in Star Coordinates and Radial Axes Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Radial axes plots are projection methods that represent high-dimensional data samples as points on a two-dimensional plane. These techniques define mappings through a set of axis vectors, each associated with a data variable, ... -
Parameterized Splitting of Summed Volume Tables
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Summed Volume Tables (SVTs) allow one to compute integrals over the data values in any cubical area of a three-dimensional orthogonal grid in constant time, and they are especially interesting for building spatial search ... -
ParSetgnostics: Quality Metrics for Parallel Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2021)While there are many visualization techniques for exploring numeric data, only a few work with categorical data. One prominent example is Parallel Sets, showing data frequencies instead of data points - analogous to parallel ... -
ProBGP: Progressive Visual Analytics of Live BGP Updates
(The Eurographics Association and John Wiley & Sons Ltd., 2021)The global routing network is the backbone of the Internet. However, it is quite vulnerable to attacks that cause major disruptions or routing manipulations. Prior related works have visualized routing path changes with ... -
A Progressive Approach for Uncertainty Visualization in Diffusion Tensor Imaging
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Diffusion Tensor Imaging (DTI) is a non-invasive magnetic resonance imaging technique that, combined with fiber tracking algorithms, allows the characterization and visualization of white matter structures in the brain. ... -
Public Data Visualization: Analyzing Local Running Statistics on Situated Displays
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Popular sports tracking applications allow athletes to share and compare their personal performance data with others. Visualizing this data in relevant public settings can be beneficial in provoking novel types of opportunistic ... -
SenVis: Interactive Tensor-based Sensitivity Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Sobol's method is one of the most powerful and widely used frameworks for global sensitivity analysis, and it maps every possible combination of input variables to an associated Sobol index. However, these indices are often ... -
SumRe: Design and Evaluation of a Gist-based Summary Visualization for Incident Reports Triage
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Incident report triage is a common endeavor in many industry sectors, often coupled with serious public safety implications. For example, at the US Food and Drug Administration (FDA), analysts triage an influx of incident ... -
Texture Browser: Feature-based Texture Exploration
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Texture is a key characteristic in the definition of the physical appearance of an object and a crucial element in the creation process of 3D artists. However, retrieving a texture that matches an intended look from an ... -
Thin-Volume Visualization on Curved Domains
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Thin, curved structures occur in many volumetric datasets. Their analysis using classical volume rendering is difficult because parts of such structures can bend away or hide behind occluding elements. This problem cannot ... -
Topography of Violence: Considerations for Ethical and Collaborative Visualization Design
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Based on a collaborative visualization design process involving sensitive historical data and historiographical expertise, we investigate the relevance of ethical principles in visualization design. While fundamental ethical ... -
