Information visualization is the use of visual and interactive representations of data to amplify cognition. Although this production is usually focused on the creation of functionalist and pragmatic visualizations, there has been an advance in the field of artistic visualization as well as physical visualization. This article reports the unfolding of an experimental discipline of physical visualization, taught in the course of Visual Design Communication at the School of Fine Arts from the Federal University of Rio de Janeiro. The three best projects performed in the discipline are described, followed by an analysis that points out the need for specific actions related to data collection and understanding; descriptive elaboration of the project; choice and use of materials; tests and evaluations regarding the transmission of knowledge and aroused feelings. It concludes that elaborating these problems will be useful to the design of data sculptures.
