Earlier this week I posted two scatterplots examining the relationship between a country's average temperature and its male residents' average height. The data show some correlation, but there probably are several of other factors affecting height as well.

The earlier plots shaded the country dots by income and region, allowing more context about the groupings of countries (hint: Europe is colder and taller).

This next version, however, proportionally sizes the dots by population, adding another layer of context (or perhaps unnecessary complexity).

The colors still represent income as categorized by the World Health Organization:

See the previous post, which includes a table with all the countries' data, here.
