Abstract

[Abstract from article]
A good statistical graphic reveals accurately and economically what the data have to say. It facilitates understanding, aids in making comparisons, and brings to the analyst's attention features of the data that merit further investigations. The purpose is to engage the analytical power of the eye-brain system, and therefore:

• information should be clear and accurate
• graphics should be minimal : their content should convey information.
• simplicity is a virtue: the less a graphic uses to tell its story, the better.

Unfortunately, most business graphics violate these principles.
