Use this diagram to explain that it is important to think carefully about what variables to display or analyse. Sometimes a ratio or difference between variables is more meaningful.

Select Population and Area from the pop-up menu to display these variables on the map. The resulting maps indicates little more than which countries are large and small. Density is more informative:

Area

Select Density from the pop-up menu to see the most densely populated countries.
