A fantastic example of horrible information visualization. Those bar charts are almost useless. The colors don't seem to correspond to anything, the ranking is apparently random, and the x-axis scale varies wildly, making cross-country comparisons an exercise in mental arithmetic.

I came here to say exactly that. They make a point of using the same colors in each chart (mostly), giving the illusion of some correspondence, but the colors mean something different for each chart. For example, "Difficult" and "Agreeable" are the same color in the first two charts.
