CompTIA Data+ (DA0-001) — Question 189

A data analyst needs to create a dashboard using the company’s yearly revenue data sets.

Which of the following would be the best way to plot the information to show the top performing region?

Answer options

• A. A line chart
• B. A waterfall chart
• C. A heat map
• D. A stacked bar chart

Correct answer: D

Explanation

A stacked bar chart is the most suitable choice as it allows for easy comparison of different regions' performances within a single visual. The other options, such as line charts and waterfall charts, do not effectively compare multiple regions simultaneously, while heat maps may not clearly delineate performance differences.
