A task-oriented view of information visualization

Much of the research in information visualization has primarily focused on providing new views and frameworks to aid users in exploring or accessing data. Very little work has been done to support users through their full analysis process--from transforming their raw data into a set of polished final results. In this pilot study, we conducted a task analysis on five experts' use of an existing information visualization system when analyzing a complex data set. Our preliminary results indicate that users conduct several tasks outside of data exploration--tasks such as preparing the data, collecting results, and gathering evidence for a presentation. In addition, they give these other tasks high importance ratings with respect to the analysis process.
