A propaganda map is used to "sway" the viewer to think one thing over another. A lot of propaganda maps are used politically.
This map uses plastic cups on a platform shaped like the US to describe the American obesity rate across the country. Each color inside the cup represents the area's obesity statistic. This map uses propaganda by shaping the McDonalds golden arches in the middle to show that McDonalds is partially to blame for America's obesity.
As I was researching more about this famous propaganda map, I found this: "Figures from 1994 are indicated on one side of the cups, and those from 2002 on the other, so that the extraordinary increase in obesity levels becomes dramatically apparent as viewers walk from left to right." I found that to be very interesting.
