Abstract : Despite the recent explosion of software development and computer programs capable of bringing dynamic visual data analytic techniques to a wide range of users, little empirical evidence has been offered to justify or support claims about the potential usefulness and efficacy of dynamic graphical data analytic procedures as a class. In the current investigation, artificial data with a known three-dimensional clustery structure was submitted to a sophisticated data 'visualizer who attempted to identify the structure in the data. Additional variables which were taken into account included (1) the number of true clouds of points present in each data set, (2) the number of data points per each cloud, and (3) the distance between pairs of clouds within a data set. Results indicate that distance between clouds relates positively to the accuracy of cloud membership judgments.
