Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Consistent color coding across all charts
Visual hierarchy ensures executives see key metrics first. Consistent color coding helps users quickly associate colors with categories. Interactive filters allow different users to drill down to their required level of detail. Data-ink ratio is important but less critical for multi-user dashboards. Annotations are useful for storytelling but not a core design principle for interactive dashboards.
