A cartogram is a type of map where states aren't sized by their area but by a different value.
                This is a map of the United States with Wyoming and New Jersey labeled.
                
                Wyoming is big because it has a large area and New Jersey is little because it has a small area.
                
                On this cartogram states are sized by the number of people living there.
                
                Now Wyoming is little because it has a small population and New Jersey is big because it has a large population.
