Despite the overwhelming evidence proving pie charts ineffectively display data, designers continue to use this deficient graphic. Two of the most prominent data visualization experts, Stephen Few and Edward Tufte, both agree that the usefulness of the pie chart is limited. “Of all the graphs that play major roles in the lexicon of quantitative communication,” Few maintains, “the pie chart is by far the least effective.” Edward Tufte is even more blunt. In The Visual Display of Quantitative Information, he wrote, “Given their low data-density and failure to order numbers along a visual dimension, pie charts should never be used.”
