CoreFlow: Extracting and Visualizing Branching Patterns from Event Sequences
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Event sequence datasets with high event cardinality and long sequences are difficult to visualize and analyze. In particular, it is hard to generate a high level visual summary of paths and volume of flow. Existing approaches ... -
Internal and External Visual Cue Preferences for Visualizations in Presentations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Presenters, such as analysts briefing to an executive committee, often use visualizations to convey information. In these cases, providing clear visual guidance is important to communicate key concepts without confusion. ... -
GraSp: Combining Spatially-aware Mobile Devices and a Display Wall for Graph Visualization and Interaction
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Going beyond established desktop interfaces, researchers have begun re-thinking visualization approaches to make use of alternative display environments and more natural interaction modalities. In this paper, we investigate ... -
Steering the Craft: UI Elements and Visualizations for Supporting Progressive Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Progressive visual analytics (PVA) has emerged in recent years to manage the latency of data analysis systems. When analysis is performed progressively, rough estimates of the results are generated quickly and are then ... -
Uncertainty Footprint: Visualization of Nonuniform Behavior of Iterative Algorithms Applied to 4D Cell Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Research on microscopy data from developing biological samples usually requires tracking individual cells over time. When cells are three-dimensionally and densely packed in a time-dependent scan of volumes, tracking results ... -
Visualizing Probabilistic Multi-Phase Fluid Simulation Data using a Sampling Approach
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Eulerian Method of Moment (MoM) solvers are gaining popularity for multi-phase CFD simulation involving bubbles or droplets in process engineering. Because the actual positions of bubbles are uncertain, the spatial ... -
Dynamic Scene Graph: Enabling Scaling, Positioning, and Navigation in the Universe
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this work, we address the challenge of seamlessly visualizing astronomical data exhibiting huge scale differences in distance, size, and resolution. One of the difficulties is accurate, fast, and dynamic positioning and ... -
Illustrative Visualization of Mesoscale Ocean Eddies
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Feature-based time-varying volume visualization is combined with illustrative visualization to tell the story of how mesoscale ocean eddies form in the Gulf Stream and transport heat and nutrients across the ocean basin. ... -
Generating Tile Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Tile maps are an important tool in thematic cartography with distinct qualities (and limitations) that distinguish them from better-known techniques such as choropleths, cartograms and symbol maps. Specifically, tile maps ... -
Understanding Indirect Causal Relationships in Node-Link Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)To find correlations and cause and effect relationships in multivariate data sets is central in many data analysis problems. A common way of representing causal relations among variables is to use node-link diagrams, where ... -
Minimum-Displacement Overlap Removal for Geo-referenced Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Given a set of rectangles embedded in the plane, we consider the problem of adjusting the layout to remove all overlap while preserving the orthogonal order of the rectangles. The objective is to minimize the displacement ... -
Linear Discriminative Star Coordinates for Exploring Class and Cluster Separation of High Dimensional Data
(The Eurographics Association and John Wiley & Sons Ltd., 2017)One main task for domain experts in analysing their nD data is to detect and interpret class/cluster separations and outliers. In fact, an important question is, which features/dimensions separate classes best or allow a ... -
Adaptable Radial Axes Plots for Improved Multivariate Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Radial axes plots are multivariate visualization techniques that extend scatterplots in order to represent high-dimensional data as points on an observable display. Well-known methods include star coordinates or principal ... -
Visual Narrative Flow: Exploring Factors Shaping Data Visualization Story Reading Experiences
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Many factors can shape the flow of visual data-driven stories, and thereby the way readers experience those stories. Through the analysis of 80 existing stories found on popular websites, we systematically investigate and ... -
Finding a Clear Path: Structuring Strategies for Visualization Sequences
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Little is known about how people structure sets of visualizations to support sequential viewing. We contribute findings from several studies examining visualization sequencing and reception. In our first study, people made ... -
Reverse-Engineering Visualizations: Recovering Visual Encodings from Chart Images
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We investigate how to automatically recover visual encodings from a chart image, primarily using inferred text elements. We contribute an end-to-end pipeline which takes a bitmap image as input and returns a visual encoding ... -
Measuring Symmetry in Drawings of Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Layout symmetry is an important and desired feature in graph drawing. While there is a substantial body of work in computer vision around the detection and measurement of symmetry in images, there has been little effort ... -
Comparative Visual Analysis of Structure-Performance Relations in Complex Bulk-Heterojunction Morphologies
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The structure of Bulk-Heterojunction (BHJ) materials, the main component of organic photovoltaic solar cells, is very complex, and the relationship between structure and performance is still largely an open question. ... -
Visualization of Delay Uncertainty and its Impact on Train Trip Planning: A Design Study
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Uncertainty about possible train delays has an impact on train trips, as the exact arrival time is unknown during trip planning. Delays can lead to missing a connecting train at the transfer station, or to coming too late ... -
Dynamic Visual Abstraction of Soccer Movement
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Trajectory-based visualization of coordinated movement data within a bounded area, such as player and ball movement within a soccer pitch, can easily result in visual crossings, overplotting, and clutter. Trajectory ...
