According to USA Today, the headquarters of over one-third of all Fortune 500 (F500) companies are located in one of six U.S. metropolitan areas: Chicago, Dallas-Ft. Worth, Houston, Minneapolis-St. Paul, New York, and San Francisco. The following chart displays the number of F500 headquarters for each of these metropolitan areas. Which of these statements are correct? Select all that apply.

Color is used in conjunction with the legend to tell the audience which bar represents each metropolitan area in this chart. This requires the audience to go back and forth between the bars and the legend to make these associations and so creates unnecessary eye travel.

Metropolitan area has six unique values, but the chart uses only three unique colors; it uses blue for both Chicago and Minneapolis-St. Paul, red for both Dallas and New York, and yellow for both Houston and San Francisco with no identified reason.

We can correct the ineffective use of color in this chart by using a single color for all bars, eliminating the legend, adding a horizontal axis title, and using horizontal axis labels to indicate the metropolitan areas.

This chart follows good practices of the choice of colors in data visualization.
