Greetings,

The Gelman link you provided was to the blog homepage, not the particular posting. When I searched on infographics, the result most relevant was from a year ago. That is hardly "recently" -- maybe you had another posting in mind????

Thanks for your continuing efforts. I enjoy your blog.

It's not the angle of the pie wedges, but the relative diameter or area of the inside colored section to the whole wedge, that encodes the variable. But yeah, not real effective, except for showing which percentage is greater, in case you can't read the numbers.

MsJulie: Here is the most relevant link from Jan 2011

Well, given the chosen representation I would even assume that the creator of the "graph" never intended to create a data graphics. As long as the perceived areas and annotated figures are not discordant, the creator should get away with it.

I guess the percentages add up to more than 100% because each respondent was allowed to say "yes" to more than one question. The answers were probably NOT mutually exclusive.

Samuel: you're surely right about allowing multiple responses. one should never use a pie chart for such data!
