 Each visual variable argument can also be specified with a data variable (e.g., a column name). What happens in that case is that the values of data variable are mapped to values of the corresponding visual variable.

 We used two variables: `size` to deform the polygons using a continuous cartogram and `fill` to color the polygons.
