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. ... -
Integrating Visual Analytics Support for Grounded Theory Practice in Qualitative Text Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present an argument for using visual analytics to aid Grounded Theory methodologies in qualitative data analysis. Grounded theory methods involve the inductive analysis of data to generate novel insights and theoretical ... -
Interactive Ambiguity Resolution of Named Entities in Fictional Literature
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Named entity recognition (NER) denotes the task to detect entities and their corresponding classes, such as person or location, in unstructured text data. For most applications, state of the art NER software is producing ... -
Interactive Regression Lens for Exploring Scatter Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Data analysis often involves finding models that can explain patterns in data, and reduce possibly large data sets to more compact model-based representations. In Statistics, many methods are available to compute model ... -
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. ... -
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 ... -
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 ... -
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 ... -
NEREx: Named-Entity Relationship Exploration in Multi-Party Conversations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Abstract We present NEREx, an interactive visual analytics approach for the exploratory analysis of verbatim conversational transcripts. By revealing different perspectives on multi-party conversations, NEREx gives an entry ... -
Nested Tracking Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Tracking graphs are a well established tool in topological analysis to visualize the evolution of components and their properties over time, i.e., when components appear, disappear, merge, and split. However, tracking ... -
Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ... -
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 ... -
Sclow Plots: Visualizing Empty Space
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Scatter plots are mostly used for correlation analysis, but are also a useful tool for understanding the distribution of highdimensional point cloud data. An important characteristic of such distributions are clusters, and ... -
Sliceplorer: 1D Slices for Multi-dimensional Continuous Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Multi-dimensional continuous functions are commonly visualized with 2D slices or topological views. Here, we explore 1D slices as an alternative approach to show such functions. Our goal with 1D slices is to combine the ... -
Stardust: Accessible and Transparent GPU Support for Information Visualization Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Web-based visualization libraries are in wide use, but performance bottlenecks occur when rendering, and especially animating, a large number of graphical marks. While GPU-based rendering can drastically improve performance, ... -
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 ... -
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 ... -
Visual Analysis of Confocal Raman Spectroscopy Data using Cascaded Transfer Function Design
(The Eurographics Association and John Wiley & Sons Ltd., 2017)2D Confocal Raman Microscopy (CRM) data consist of high dimensional per-pixel spectral data of 1000 bands and allows for complex spectral and spatial-spectral analysis tasks, i.e., in material discrimination, material ... -
Visual Comparison of Eye Movement Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In eye tracking research, finding eye movement patterns and similar strategies between participants' eye movements is important to understand task solving strategies and obstacles. In this application paper, we present a ...
