Pie plots

Pie plots (sometimes called pie charts) are extremely popular, but often difficult to interpret. They are just bar plots converted into polar coordinates, and humans are generally worse at perceiving angles accurately compared to lengths.

Following on from the scotch whisky dataset in the last chapter, here's another dataset from the Health Survey for England, this time on alcohol consumption in English men aged 16 or more. Pie segments and bar heights represent percentages of responders.

Look at the pie plot and the bar plot and determine which statement is true.
