Constructive Visualization

This is an ongoing project.

The accessibility of infovis authoring tools to a wide audience has been identified as one of the major research challenges. A key task of the authoring process is the development of visual mappings. While the infovis community has long been deeply interested in finding effective visual mappings, comparatively little attention has been placed on how people construct visual mappings. In this paper we present the results of a study designed to shed light on how people spontaneously transform data into visual representations. We asked people to create, update and explain their own information visualizations using simple materials such as tangible building blocks. We learned that all participants, most of whom had no experience in visualization, were readily able to create and talk about their own visualizations. On the basis of our observations, we discuss the actions of our participants in the context of the development of their visual representations and their analytic activities. From this we suggest implications for tool design that can enable broader support for infovis authoring.
