Many of the graphics here violate visual best practices, which can make them very misleading (the scatter plot in particular). The most egregious is the use of a log-scale on three of the graphics, which isn't highlighted at all. Humans don't compare and interpret log scales well (see The Elements of Graphing Data by Cleveland, etc.). I would've much rather seen percentages (say on return on investment) or break out the analysis into tiers that were more comparable.
