Optimizing Stepwise Animation in Dynamic Set Diagrams
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A set diagram represents the membership relation among data elements. It is often visualized as secondary information on top of primary information, such as the spatial positions of elements on maps and charts. Visualizing ...
Investigating the Manual View Specification and Visualization by Demonstration Paradigms for Visualization Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Abstract Interactivity plays an important role in data visualization. Therefore, understanding how people create visualizations given different interaction paradigms provides empirical evidence to inform interaction design. ...
Bridging the Data Analysis Communication Gap Utilizing a Three-Component Summarized Line Graph
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Communication-minded visualizations are designed to provide their audience-managers, decision-makers, and the public-with new knowledge. Authoring such visualizations effectively is challenging because the audience often ...
VIAN: A Visual Annotation Tool for Film Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
While color plays a fundamental role in film design and production, existing solutions for film analysis in the digital humanities address perceptual and spatial color information only tangentially. We introduce VIAN, a ...
Towards Glyphs for Uncertain Symmetric Second-Order Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Measured data often incorporates some amount of uncertainty, which is generally modeled as a distribution of possible samples. In this paper, we consider second-order symmetric tensors with uncertainty. In the 3D case, ...
Toward Understanding Representation Methods in Visualization Recommendations through Scatterplot Construction Tasks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Most visualization recommendation systems predominantly rely on graphical previews to describe alternative visual encodings. However, since InfoVis novices are not familiar with visual representations (e.g., interpretation ...
A Framework for GPU-accelerated Exploration of Massive Time-varying Rectilinear Scalar Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We introduce a novel flexible approach to spatiotemporal exploration of rectilinear scalar volumes. Our out-of-core representation, based on per-frame levels of hierarchically tiled non-redundant 3D grids, efficiently ...
InsideInsights: Integrating Data-Driven Reporting in Collaborative Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Analyzing complex data is a non-linear process that alternates between identifying discrete facts and developing overall assessments and conclusions. In addition, data analysis rarely occurs in solitude; multiple collaborators ...
A Random Sampling O(n) Force-calculation Algorithm for Graph Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper proposes a linear-time repulsive-force-calculation algorithm with sub-linear auxiliary space requirements, achieving an asymptotic improvement over the Barnes-Hut and Fast Multipole Method force-calculation ...
Examining Implicit Discretization in Spectral Schemes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Two of the primary reasons rainbow color maps are considered ineffective trace back to the idea that they implicitly discretize encoded data into hue-based bands, yet no research addresses what this discretization looks ...
