Alison Snieckus, our presenter this week (Thursday at noon EST) on #VizMath, suggested we collect confusing graphs as well as helpful ones. I found a few, but liked this one from a blog:

The blogger who shaded it pointed out how it was misleading. The point was to show how most tweets are done directly through Twitter. But, as the blogger noted, the percentages add up to 138%! And, the categories are not worked out well at all. This is clearly a graph that is sloppy and gives math a bad name. So, what was the purpose of this graph?
