Proportion, transparency, coherence, order, tranquility....these are the results of data that is properly layered and separated. An information graphic with layering and separation affords greater visual interpretation. The independent elements become more organized and discernible. The relationships between data points are more clearly defined. Chaos disappears. Tufte is essentially saying that layering and separation produces simplicity of form and shape and visually appealing data. He writes about the removal of "clutter" and "noise reduction" (Tufte 62).
