DA0-002 Visualization and Reporting Practice Question
A retail analyst is preparing a one-page executive dashboard. The CEO wants to see month-over-month revenue growth, while the operations director wants to monitor daily order volume. The analyst decides to use a bullet chart for the revenue growth and a line chart for daily order volume. Which design principle is best demonstrated by this choice?
⚠ Common exam trap
The trap here is assuming that consistency in chart type is more important than matching the visualization to the data and audience.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Selecting chart types based on the audience and the nature of the data.
The analyst selects a bullet chart for revenue growth because it effectively compares a measure to a target, and a line chart for daily order volume because it clearly shows trends over time. This aligns each visualization with both the data's nature and the audience's specific needs, which is a fundamental best practice in dashboard design.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Maximizing the number of charts on the dashboard to provide comprehensive data.
Why it's wrong here
The scenario describes a one-page dashboard with two specific charts, not an attempt to maximize chart count. Adding more charts would clutter the dashboard and distract from the key metrics. Effective dashboards prioritize clarity and focus, not quantity. The analyst's choice is about appropriateness, not volume.
- ✗
Using color to encode all data points regardless of chart type.
Why it's wrong here
While color can be useful, the scenario does not mention color usage. The decision to use different chart types is about matching the visualization to the data and audience, not about color encoding. Applying color indiscriminately could actually hinder readability. Therefore, this option does not describe the principle illustrated.
- ✗
Using a single chart type for all metrics to maintain consistency.
Why it's wrong here
Using one chart type for all metrics ignores that different metrics have different data characteristics and audience needs. A bullet chart is suited for comparing a measure against a target, while a line chart shows trends over time. Forcing both into the same chart type would reduce clarity and fail to meet the CEO's and operations director's distinct requirements.
- ✓
Selecting chart types based on the audience and the nature of the data.
Why this is correct
The analyst matches the bullet chart to the CEO's need for a quick comparison of revenue growth against a target, and the line chart to the operations director's need to see daily order volume trends. This demonstrates selecting visualizations based on both the data's characteristics and the audience's purpose, which is a core principle of effective dashboard design.
