See What You Know: Analyzing Data Distribution to Improve Density Map Visualization
Enrico Bertini, Alessio Di Girolamo, Giuseppe Santucci · IRIS Research product catalog (Sapienza University of Rome) · 2007
Density maps allow for visually rendering density differences, usually mapping density values to a grey or color scale. The paper analyzes the drawbacks arising from the commonly used strategies and introduces a novel technique able to improve the overall mapping process. The technique is driven by statistical knowledge about the density distribution and a set of quality metrics allows for validating, in an objective way, its effectiveness.
