Pie charts are already hard for people to interpret correctly. Proportional interpretation depends on position in the circle. By using hexagons the area of the fuel source is no longer related to the value. All you can really see is that gasoline dominates expenditures.
Additionally, the size of the hexagon used to represent total household expenditures is not easily discernible from one state to another. Only the number in the center helps, which indicates this should be a table.

No… it’s easy as pie. Pie charts are good.
