Reader Jeannie C. succeeded in coaxing me to put up an infographics poster. It's predictable that such a thing would eventually arise: an infographics about infographics...
If you click on Ivan's link, you will find the real "data" behind this infographics.
Let's do spot the "errors".
I'll go for the easy one. 22+24+24+32 = 102. Typically, one could call this rounding error. But it has always mystified me why the designer does not "round" down the individual numbers such that the total adds to 100%. In either case, we have to accept a small amount of imprecision. (For example, 23+23+23+31 = 100).
Your turn next...
PS. I'm reading this chart as a parody on the infographics genre.
Ivan pointed out that my contribution above is illegitimate since there weren't any rounding. So, my turn again: the yellow bars are not to scale, China is not 4 times the length of U.S.
