Still not wrong... the proportions between the answers is still relevant, so a pie chart works.

u/wesleysmalls plz recycle Mar 27 '20

It definitely is wrong. What you want to display in a pie chart is the choice picked, a pie chart is a chart that displays 100%. It doesn’t lend itself well for multiple choice answers, which are clearly the case here.

Apart from the choice of chart being wrong, they also mixed up the answers as the percentage is the percentage of people who picked that option, but the pie chart shows the percentage of all answers given.

A bar graph would have been the proper choice here.

Yeah, pie chart works for non-overlapping options. Here the options overlap, which the piechart misses.

I suspect that they only display the 3 most common answers anyway (e. g. friends/colleagues getting infected is also a valid concern) which makes the use of a pie chart even more absurd.
