Distributed database performance is often unpredictable due to issues such as system complexity, network congestion, or imbalanced data distribution. These issues are difficult for users to assess in part due to the opaque ...
Refinery: Visual Exploration of Large, Heterogeneous Networks through Associative Browsing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Browsing is a fundamental aspect of exploratory information-seeking. Associative browsing represents a common and intuitive set of exploratory strategies in which users step iteratively from familiar to novel bits of ...
Visual Debugging Techniques for Reactive Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Interaction is critical to effective visualization, but can be difficult to author and debug due to dependencies among input events, program state, and visual output. Recent advances leverage reactive semantics to support ...
Lyra: An Interactive Visualization Design Environment
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present Lyra, an interactive environment for designing customized visualizations without writing code. Using drag-and-drop interactions, designers can bind data to the properties of graphical marks to author expressive ...
imMens: Real-time Visual Querying of Big Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Data analysts must make sense of increasingly large data sets, sometimes with billions or more records.We present methods for interactive visualization of big data, following the principle that perceptual and interactive ...
Selecting Semantically-Resonant Colors for Data Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce an algorithm for automatic selection of semantically-resonant colors to represent data (e.g., using blue for data about ''oceans'', or pink for ''love''). Given a set of categorical values and a target color ...
Authoring Narrative Visualizations with Ellipsis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Data visualization is now a popular medium for journalistic storytelling. However, current visualization tools either lack support for storytelling or require significant technical expertise. Informed by interviews with ...
