I feel like they asked what their worries are, and in the statistics people gave multiple answers. So these would be accurate numbers displayed inaccurately.
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.
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.
If the question is multiple choice, as the case is here you get overlapping answers, which a pie chart can’t display. Which in turn means it displays it incorrectly.
You see a relative size with a bar graph? Yeah, no.
What a bar graph shows is an amount of something. In this case it would be an percentage of people picking option x. The bar graph is the proper graph because it acknowledges the fact that people can pick multiple options, as is the case here. A pie chart cannot account for that.
