Visualization enables viewers to understand and interpret complex data using graphical form, but the increasing complexity and size of today's datasets means that mere visual representations are no longer enough. While interaction is typically part of the definition of information visualization research, it is often overlooked or given only cursory attention in favor of the visible output of a visualization technique.
In this talk, I will describe my work on characterizing and utilizing interaction in order to enable a true visual exploration process: the interactive use of visualizations to form hypotheses, find evidence, and draw conclusions about datasets. I will go into detail on the different components of this process, and I will show how it makes many of the aforementioned problems of complexity and size tractable. Furthermore, I will give concrete examples and demonstrations of my work in the area, including the DataMeadow and ScatterDice tools for multidimensional analysis, the ZAME system for large-scale graph visualization, and the Color Lens technique for colorscale optimization. I will also outline a research agenda based on harnessing and improving interaction for visual exploration.
