*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract
--------------
Interactivity can be added to data visualizations to enable users to gain insight into large, complex datasets. The ultimate goal of many of interactive data visualization tools is to enable users to explore their data visually through an iterative process, without requiring them to program. A majority of the existing data visualization tools enable users to interact with control panels, dropdown menus, and check boxes to inject their questions and hypotheses about the data. This has been a really powerful way to incorporate users into visual data exploration process. However, visualization tools are getting more advanced and complicated. As functionality grows, the naive approach of making more control panels, additional menus, and longer drop-down lists of choices does not scale. Thus, we need to investigate incorporating other interaction paradigms to data visualization tools.
In my research, I am investigating a novel interaction paradigm for visual data exploration called ``visualization by demonstration'’. Through this work, I define principles of visualization by demonstration and indicate the feasibility of this interaction paradigm for visual data exploration. I also provide empirical evidences describing the trade-offs of the visualization by demonstration. In my work, I indicate how visualization by demonstration can enable healthcare domain experts to perform real world tasks such as data grouping. Finally, I design and develop a toolkit that enables developers to incorporate visualization by demonstration into their interfaces.
