Unclear on the pie chart concept
The pie-chart problems that Melbourne’s Herald-Sun had with their bogus polls appear to be spreading. This one is from wtfviz.net (via @TimHarford), and apparently comes from Britain’s TES magazine.
I suppose it’s encouraging that this sort of thing seems only to happen for bogus polls, not for actual data.
