CompTIA Data+ (DA0-001) — Question 247

An analyst compiled data on the preferred color of various models of cars over a period of time. Which of the following visualizations is best way to present this information?

Answer options

• A. Bubble chart
• B. Stacked chart
• C. Line graph
• D. Heat map

Correct answer: B

Explanation

The stacked chart is the best choice as it allows for the comparison of different categories (car colors) over the time period while showing the total number of car models. Other options like the bubble chart and line graph do not effectively represent the multiple categories within the same time frame, and the heat map is better suited for showing density rather than changes over time.
