Abstract:

Data visualization research often seeks to help solve real world problems across application domains, from biomedicine to engineering.
There is considerable merit in such endeavors, which often help advance knowledge in these application domains. Beyond these contributions, as we work alongside domain experts, we also have a unique opportunity to observe qualitatively and analyze how these clients interact with the data through our tools and paradigms. Thus, we have a rare opportunity to better ground data visualization theory on these observations. In this talk, I will examine how working with real world data and problems can point out specific gaps in our theoretical knowledge, can challenge underlying assumptions in the data visualization field, and can lead to new insights and theoretical guidelines. I will focus on several theoretical contributions grounded in this experience, from activity-centered design to visual scaffolding, the details-first paradigm, and visual explainability in artificial intelligence. Last, I will reflect on the lessons learned through this experience, with particular emphasis on the barriers our field poses to new theoretical contributions.
