Edward Tufte, in The Visual Display of Quantitative Data, wrote "the only worse design than a pie chart is several of them."
Howard Wainer of the Educational Testing Service stated in a 1987 Independent Expert Review of EIA Statistical Graphs policies that "the use of pie charts is almost never justified" and that they "ought not to be used." Wainer recommended to EIA that dot charts be used instead of pie charts in EIA products.
