What a horrible, horrible headline. Mary's analysis is incredibly detailed, extrememly informative, and FREE. This link-bait headline chose to ignore all the content and focus exclusively on the fact that the plots are ugly. Strangely enough, I managed to get through the slideshow without falling asleep, and I even was able to read her (quite well laid out) graphs and understand her points.

The author even acknowledged this; the first paragraph does nothing but extoll the value of the analysis. The headline, though, is pure linkbait.

Even worse, replacing a bar chart, where height scales linearly with the metric and is easily comparable across bars, with a bubble plot, which is very hard to use to compare sizes (tiny changes in radius cause a huge change in volume, not so easy to see that), is simply bad design and obfuscates the point. Color me not impressed.

Shame on you, Bloomberg. You should be better than that.
