Light entertainment: a self-referencing chart

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.



I'm glad you are analyzing my graphic so closely! Some clarification: It is sheer coincidence that those numbers add up to anything close to 100%. Each chart is actually baed on every infographic, so each chart is out of 100%. Because one single infographic can have multiple charts. Does that make sense? :) -ivan


Ivan: I should put "errors" in quotes. I'm interpreting your chart as a soft parody on the state of infographics.

I get how you are counting the types of charts, and why it won't add to 100%. Glad it gave me an excuse to rant about the common practice of showing "rounding errors" (even if it doesn't apply to you.)


gotcha! cool! :)

Nice information! I would say I am impressed with the research you made to make this article awesome and hope to read more about this. Thanks for sharing.

Haha! Nice - an infographic about an infographic. But of course, every single one of these graphics really takes a lot of effort. It's more than just designing with the right colors and font styles. Researching for information is all important. Anyway, what you did here is a cool design!

Rounding is overrated anyway. But it does make sense for accuracy purposes.
