DA0-002 Visualization and Reporting Practice Question
An analyst creates a dashboard with a large amount of decorative graphics and background images. According to CompTIA Data+, which design principle is being violated?
⚠ Common exam trap
Test-takers frequently confuse 'decorative graphics' with 'visual hierarchy' or 'color coding,' but CompTIA Data+ specifically tests the data-ink ratio as a principle for minimizing non-data elements to enhance readability.

Correct answer & explanation
✓
Data-ink ratio
The data-ink ratio, a concept from Edward Tufte, states that a visualization should maximize the proportion of ink used to represent actual data relative to total ink used. By adding excessive decorative graphics and background images, the analyst reduces this ratio, making the dashboard less efficient and potentially obscuring the data. CompTIA Data+ emphasizes minimizing non-data ink to improve clarity and insight extraction.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Visual hierarchy
Why it's wrong here
Visual hierarchy prioritizes important elements, not the amount of ink.
- ✓
Data-ink ratio
Why this is correct
The data-ink ratio is reduced by unnecessary decorative elements.
- ✗
Appropriate precision
Why it's wrong here
Precision relates to number formatting, not decorative elements.
- ✗
Consistent color coding
Why it's wrong here
Color consistency is not directly related to decorative graphics.
