The following bar graph gives the percent of owners of three brands of trucks who are satisfied with their truck. What is wrong with the way information is presented in this graph?

There should be a title and a variable label on the horizontal scale.

The vertical scale should begin at 0 so the Chevrolet bar doesn't look disproportionately larger than Ford and Toyota.

The vertical scale should have been measured in number of owners satisfied instead of percent of owners satisfied.

This information should have been displayed in a pie chart.
