This is a Proportional Circle Map. I took this map from the same website I got the Classed Choropleth Map from. The maps where used to show the same data mapped in two different ways. So this map also shows the spending by overseas residents in 2003. Proportional circle maps use circles for each different country. The legend shows that the smallest circle stands for 5 million. As the circles increase so do their amounts. If there is no circle in a country then there was no spending recorded.
