A number of three-dimensional information visualization designs have been invented during the last years. However, comparisons of such designs have been scarce, making it di cult for application developers to select a suitable design. This paper reports on a case study where three existing visualization designs have been implemented and evaluated. We found that the three information visualization designs have inherent problems when used for visualizing di erent data sets, and that certain tasks can not be supported by the designs. A general methodology for evaluation is presented, which comprises evaluation of suitability for di erent data sets as well as evaluation of support for user tasks.
