"The purpose of visualization rules is to help insure that structures in the data are faithfully represented in the image, and that perceptual artifacts are not erroneously interpreted as data features. To accomplish this goal, it is important to understand how the human observer processes spatial variations of luminance and color, and how variations in the physical representation affect its interpretation."

The importance of human perceptual and cognitive mechanisms in visualization is obviously. Representations with the same mathematical relations could look very different perceptually and could lead to very different interpretations.

Rogowitz and Treinish identified two classes of rules which are important for the visualization process:
