See solution.

bar graph

We will describe how the graph is misleading and how someone might misinterpret it. Note that the scale on the vertical axis has very small increments. Therefore, someone might believe that the annual sales more than tripled from 2010 to 2013, when actually, it increased by only about $4 million. Please note that we are only showing one of the many possible interpretations.
