"I’ve written at length in the past about the failures of pie charts and circular dashboard gauges, so I’ll keep my comments brief about them here. Although the evidence of a pie chart’s dysfunction is hard to ignore when you actually take a moment to inspect it, nothing that I teach is met with such fierce opposition as my low opinion of them." - Stephen Few
The epigraph is from an article published by Stephen Few, Perceptual Edge: the Visual Business Intelligence Newsletter (March/April/May 2010). It serves as a good enough introduction to that essay on circular graphs...pie charts. For the circular displays he includes alternative displays of the same data and provides rich discussions. I found it an interesting read.
