Toward a Statistical Knowledge Network (2004)
(2005)
Statistics support planning and decision making and enormous efforts are made to collect data and produce statistics at all levels of governance. An important principle of democratic societies is that government statistics ...
Representing Unevenly-Spaced Time Series Data for Visualization and Interactive Exploration (2005)
(2005)
Visualizing time series data is useful to support discovery of relations and patterns in financial, genomic, medical and other applications. In most time series, measurements are equally spaced over time. This paper discusses ...
Hear the PatternInteractive Sonification of Geographical Data Patterns (2004)
(2005)
In this paper we describe our investigation of using interactive sonification (non-speech sound) to present the geographical distribution pattern of statistical data to vision impaired users. We first discuss the design ...
Data Exploration with Paired Hierarchical Visualizations: Initial Designs of PairTrees (2003)
(2005)
Paired hierarchical visualizations (PairTrees) integrate treemaps, node-link diagrams, choropleth maps and other information visualization techniques to support exploration of hierarchical data sets at multiple levels of ...
Enabling Commuters to Find the Best Route: An Interface for Analyzing Driving History Logs (2001)
(2005)
This paper describes a prototype interface design for an automobile driving history log. It allows drivers to choose the best route among several alternatives for their common trips. Recorded data includes time to complete ...
Listening to Maps: User Evaluation of Interactive Sonifications of Geo-Referenced Data (2004)
(2005)
In this paper, we summarize the Auditory Information Seeking Principle (AISP) (gist, navigate, filter, and details-ondemand). To improve blind access to geo-referenced statistical data, we developed several interactive ...
'I Hear the Pattern' Interactive Sonification of Geographical Data Patterns (2004)
(2005)
In this paper we describe our investigation of using interactive sonification (non-speech sound) to present the geographical distribution pattern of statistical data to vision impaired users. We first discuss the design ...
Extending the Utility of Treemaps with Flexible Hierarchy (2004)
(2005)
Treemaps is a visualization technique for presenting hierarchical information on two dimensional displays. Prior implementations limit the visualization to pre-defined static hierarchies. Flexible hierarchy, a new capability ...
Broadening Access to Large Online Databases by Generalizing Query Previews (2000)
(2005)
Companies, government agencies, and other types of organizations are making their large databases available to the world over the Internet. Current database front-ends do not give users information about the distribution ...
Interactive Pattern Search in Time Series (2004)
(2005)
The need for pattern discovery in long time series data led researchers to develop algorithms for similarity search. Most of the literature about time series focuses on algorithms that index time series and bring the data ...
