We discuss the evolution of the NIST Information Retrieval Visualization Engine. This prototype employs modern interactive visualization techniques to provide easier access to a set of documents resulting from a query to a search engine. The motivation and evaluation of several design features, such as keywork to concept mapping, explicit clustering, the use of 3D vs. 2D, and the relationship of visualization to logical structure are described. In particular, the result of an extensive usability experiment show how visualization may lead to either increased or decreased cognitive load.
