When constructing a graph that compares the land areas of the five largest countries, you choose to depict the five areas with squares of different sizes. If the squares are drawn so that the areas are in proportion to the areas of the corresponding countries, is the resulting graph valid? Why or why not?

No, using area in graphs is always misleading.

Yes, using area in graphs is never misleading.

Yes, the variable of interest is two-dimensional.

No, the variable of interest is two-dimensional.

Yes, the variable of interest is two-dimensional.

If you are making a graph about the area of a country, that is a two dimensional measurement. It would be ok to make a graph that is also 2 dimensional.
