It wasn’t immediately popular, but the pie chart, as it was later called, gave visual metaphor to a concept that numbers had difficulty conveying. It became the default means of collating and displaying data pictorially. Unfortunately, these days few people know which types of data are appropriate for the chart, or even for visualizing at all. The pie chart is intended to display proportions of a whole within a single, small data set, but overzealous Excel users dump in large data sets or stack multiple pies. The resulting complex defeats the purpose of using a picture: simplification. The charting features of Excel, which has had its share of critics — see Edward Tufte’s scathing essay on its flaws — were only the beginning.
