That graph is hard to read. The colors can be confusing for many with not-so-perfect eyesight, especially some that may have slight Daltonism (color blindness), like my wife. She cannot detect the differences between some of the dark colors and true black.

It should be divided into two graphs, imports and domestics, then the bars can be wider and easier to read. Using a pie graph is also easier to read and understand, although it will take up more visual space. Add the numeric table with the numbers per vehicle is a better idea, because most technical information is based on numbers, not just color bars.
