This graphic by commenting platform DISQUS, arguing that higher quality online discussions come from those using pseudonyms, splits the percentage of comments by identity into pseudonyms, anonymous, and real names. Is it a bubble chart? A pie? A coincidental bowl of jello? Actually, it looks like the height of each section represents the three values, so it's a misshapened bar chart of sorts. Oi.
It's trying so hard to look good that it comes across clunky and awkward.
If anything, they should have focused on the quality signals data on the left. Wouldn't that have been more interesting? Have at it in the comments.
