Automated understanding of data visualizations
… system which we evaluate on 202 MASSVIS data visualizations. For the last two objectives, we curate a more diverse and complex dataset, Visually. We devise a computational approach that automatically outputs textual and visual elements predicted representative of the data visualization …

Designing interactive visualizations by demonstration
… direct manipulation mechanisms for authoring visualizations, but they are largely restricted to static output. To author interactive visualizations, users must instead turn to textual specification, but such approaches impose a higher technical burden than their graphical counterparts. To …

Effective Features of Algorithm Visualizations
… you can increase pedagogical value of algorithm visualizations. We believe that a pedagogically successful visualization, besides actively engaging participants, also requires certain other key features. We compared several existing algorithm visualizations for the purpose of identifying features …

Interactive visualizations to improve Bayesian reasoning
… findings from three experiments point to visualizations being a rich area to mine, and prime candidate for expanding the toolbox of techniques that can be used to more accurately elicit the predictions of judges whose expertise lies beyond the realm of statistics.

Visualizations for mental health topic models
… and transcript-reading. Four simple and familiar visualizations were developed to present the model data: 1) a list of conversation topics, 2) a donut chart of topic percentages, 3) a line chart of topic trends, and 4) a scatter plot of specific topic points in the text. Our hypothesis is that …

Opus : exploring publication data through visualizations
… At each scale, Opus provides benchmarked visualizations that facilitate understanding the work of scholars in a social, generational, geographic, and institutional context. We conducted two user studies with a small group of potential users that show supporting evidence for the benefits of …

Investigating the efficacy of terrorist network visualizations
… clusters. To test the effectiveness of the visualizations, an experiment was conducted in which participants exploited matrix and node-link visualizations constructed from a surrogate terror data set. The objectives of this experiment were to test the effectiveness of the node-link …

Cilkpride : always-on visualizations for parallel programming
… Cilkpride, an IDE plug-in that uses always-on visualizations to show programmers information on on their parallel program directly inside their IDE. Cilkpride runs a race checker and program profiler every time code is changed and immediately displays output to make programmers always aware of …

System design visualizations for synthesizing intent specifications
… An approach to using existing system design visualizations to aid system verification and validation in the early design stages is described. These commonly used system design visualizations are used to create and intent specification in a systems engineering development environment known as …

Object-centric temporal navigation for dynamic information visualizations.
… temporal navigation for time-varying information visualizations. In our approach, navigation through time is controlled by interacting directly with any data item, enabling simultaneous exploration of the time dimension while focusing on the changing item. Subtle visualizations of a data item’s …

Towards an automated system for evaluation of visualizations
… towards automating the process of evaluation of visualizations, called the Framework for the Evaluation of VizTools (FEV), was developed and is presented in this thesis. The FEV Framework combines, guidelines, scenarios, and tasks, generated by an extensive literature review, into an easy to use …

Humanizing Computational Literature Analysis Through Art-Based Visualizations
<p>Inequalities in gender representation and characterization in fictional works are issues that have long been discussed by social scientists. This work addresses these inequalities with two interrelated components. First, it contributes a sentiment and word frequency analysis task focused on …

Frame of Reference and Navigation Through Document Visualizations
The data revealed a strong influence of spatial ability on performance, suggesting that information navigation is more difficult for those with lower spatial ability. Tool and strategy choice likely played a role in the high variability observed in the data, but the flexibility allowed subjects in …

Assisting data exploration via in-situ adaptive visualizations
… from genuinely capitalizing on insights from visualizations. The two biggest challenges we identify are the lack of task support and disconnected workflow. Visual analytics tools lack task support because they do not actively suggest insights to the users, requiring users to pick each …

Display blocks : cubic displays for multi-perspective visualizations
This thesis details the design, execution and evaluation of a new type of display technology, known as Display Blocks. Display Blocks are a response to two major limitations of current displays: visualization and interaction. Each device consist of six organic light emitting diode screens, arranged …

Democratizing Details-on-demand Data Visualizations at Scale
… toolkits, building new details-on-demand data visualizations remains hard especially for large datasets. This thesis proposes new tools and systems to “democratize” details-on-demand-based data visualizations, i.e., to make it much easier to build such applications at scale. The main approach …
