This paper presents the case for Information Visualization (IV) to be a central, integrated component of study in Information Science. We summarize the current state of IV within iSchools, the market demand for IV skills, the intellectual contributions of IV to the field of Information Science and the potential intellectual contributions of Information Science to the field of IV. We conclude with three, non-exclusive scenarios for the inclusion of IV into the iSchool curriculum as first steps toward realizing this: integration throughout the curriculum, a core course, and a specialization tract.
