Improving 2D Scatterplots Effectiveness through Sampling, Displacement, and User Perception
Enrico Bertini, Giuseppe Santucci · Ninth International Conference on Information Visualisation (IV'05) · 2006
In this paper we present a novel, hybrid, and automatic strategy whose goal is to reduce the 2D scatter plot cluttering. The presented technique relies on a combination of nonuniform sampling and pixel displacement and it is driven by perceptual results coming from a suitable user study. The same results are used to define precise quality metrics that allow for validating our approach.
