Answer:
The map misrepresents the scale of orange production in the United States, because even in the U.S. is an important orange producer, the map conveys the idea that the U.S. as a whole is a producer, when it only produces oranges in a few states, with almost the entirety of the production being located in Florida.
A more accurate map would clarify this in a textbox or a note, or would have the state of Florida colored in a way that highlights that the production of oranges in the U.S. comes almost exclusively from this state.
