A pie cartogram is less useful than a pie chart

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I am not a fan of pie charts. But there is an even less useful one called a pie cartogram, as shown above. For a pie chart each wedge has a cut beginning at the center of the circle and extending to the rim. The cartogram removes that requirement so comparisons cannot be easily made via angles. All we have is areas.

 

Pie cartograms are described by eric at Stories & Stats on August 18, 2023 in an article titled Pie cartograms. An article at TYWKIWDBI on August 10, 2024 titled How do you slice a pie… chart? has another example.

 

 

I think that a bar chart, as shown above, is better for comparisons than a pie chart.
