That's a disappointing chart from the economist. When you have a lot of points, you can't show them as dots that occlude other dots, or the reader can't get much more of a sense than 'none / some / lots'. What you need to do is bucket by region and do a background heatmap with small dots added, or use a different level of opacity on the dots.

There aren't that many points. It looks fine to me. (But I agree that is a common mistake.)
