Visualizing Interchange Patterns in Massive Movement Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely available nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for ...
Small Multiples, Large Singles: A New Approach for Visual Data Exploration
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a novel visual exploration method based on small multiples and large singles for effective and efficient data analysis. Users are enabled to explore the state space by offering multiple alternatives from the ...
ExPlates: Spatializing Interactive Analysis to Scaffold Visual Exploration
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Visual exploration involves using visual representations to investigate data where the goals of the process are unclear and poorly defined. However, this often places unduly high cognitive load on the user, particularly ...
Augmenting Visualization with Natural Language Translation of Interaction: A Usability Study
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
As visualization tools get more complicated, users often find it increasingly difficult to learn interaction sequences, recall past queries, and interpret visual states.We examine a query-to-question (Q2Q) supporting system ...
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 ...
TrajectoryLenses - A Set-based Filtering and Exploration Technique for Long-term Trajectory Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The visual analysis of spatiotemporal movement is a challenging task. There may be millions of routes of different length and shape with different origin and destination, extending over a long time span. Furthermore there ...
EvalBench: A Software Library for Visualization Evaluation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
It is generally acknowledged in visualization research that it is necessary to evaluate visualization artifacts in order to provide empirical evidence on their effectiveness and efficiency as well as their usability and ...
Visual Analysis of Set Relations in a Graph
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Many applications can be modeled as a graph with additional attributes attached to the nodes. For example, a graph can be used to model the relationship of people in a social media website or a bibliographical dataset. ...
