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 ...
Constructing and Evaluating Visualisation Task Classifications: Process and Considerations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Categorising tasks is a common pursuit in the visualisation research community, with a wide variety of taxonomies, typologies, design spaces, and frameworks having been developed over the last three decades. While these ...
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 ...
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 ...
Cycle Plot Revisited: Multivariate Outlier Detection Using a Distance-Based Abstraction
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
The cycle plot is an established and effective visualization technique for identifying and comprehending patterns in periodic time series, like trends and seasonal cycles. It also allows to visually identify and contextualize ...
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 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 ...
Graffinity: Visualizing Connectivity in Large Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Multivariate graphs are prolific across many fields, including transportation and neuroscience. A key task in graph analysis is the exploration of connectivity, to, for example, analyze how signals flow through neurons, ...
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 ...
Comparing Personal Image Collections with PICTuReVis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Digital image collections contain a wealth of information, which for instance can be used to trace illegal activities and investigate criminal networks. We present a method that enables analysts to reveal relations among ...
