Tufte Chapter 3 Response Layering and Separation

By on

On page 53 Tufte introduces the topic saying that to avoid confusion and clutter separation and layering reduce noise and enriche content of displays. These design devices are used to distinguish various aspects of the data so that they don't become noise and clutter.

"Layering of data, often achieved by felicitous subtraction of weight, enhances representation of both data dimensionality and density on flatland."

Tufte shoes that signal to noise ratio is critical to reduce viewer fatigue(pg 62) and improve accuracy of readings.

What Tufte seems to be getting at with layering and separation is that the space between objects by their creation, and the space taken up by the objects created has a heavy impact on information graphics. Using bold, thick lines, clunks things up by leaving less separation and makes things harder to scan through effectively. The concept that Tufte kept coming back to was Albers' "1+1= 3" concept. This concept explained that "one line plus one line results in many meanings" and that it's all about how the images are arranged that brings out the meaning within them (pg. 61).
