But that is still not an accurate view, since the number of independents, democrats, and republicans aren't the same.

- r00fus 15y agoCouldn't you encode the sizing with the size of the pie? ie, if Independents are the smallest group, they should be a smaller circle. In this manner, area allows for accurate comparison (it could be that more Republicans disapprove of direct voting than Independents approve for example).
- baconner 15y agoYou could do that, but then you compound the problem of comparing the size of slices with an additional size of circle comparison. Humans aren't good at comparing size between these kind of shapes. We're much better at comparing rectangular shapes. You'd be much better off splitting the visualization into two bar charts - one for the % of group calculation and one for the total count of people calculation.
- nollidge 15y agoThat doesn't mean it's inaccurate, that means it's emphasizing the comparison between relative numbers rather than absolute numbers. If it was the way you wanted, then the percentages would be difficult to compare.
- sesqu 15y agoNot really. The chart type that incorporates that information is called a mosaic chart, and is one of my favorites.
