So far, information visualizations, i.e., graphical representations of huge amounts of abstract data which do not have a natural visual representation, have mainly been used to support information-retrieval tasks.In this paper we investigate whether information visualizations are also suitable to foster tasks that focus on knowledge acquisition or learning.In addition, we address the issue of how information visualizations have to be designed to be efficient learning tools.We conducted an experimental study which provided evidence that information visualizations can foster knowledge acquisition and that 2D-information visualizations are better suited for knowledge acquisition than 3D-ones.In addition, we found slight performance improvements due to using color to code information.
