Just a note that pie charts are not well regarded in this application.

Stephen Few, “Save the Pies for Dessert” (https://www.perceptualedge.com/articles/visual_business_inte...)

Edward Tufte, “The only worse design than a pie chart is several of them.”

The “1% other” is more compelling.

The link I shared wasn't even a pie chart, so when I said "pie chart" I was speaking in a colloquial sense.
