DA0-002 Visualization and Reporting Practice Question
An executive dashboard must display high-level KPIs such as current revenue, profit margin, and customer count. Which visualization type is most appropriate for each KPI?
⚠ Common exam trap
DA0-002 often tests the distinction between KPI cards (value + variance) and other visualizations like gauges or sparklines, tempting candidates to choose a more 'visual' chart when a simple card is the best practice for executive KPIs.

Correct answer & explanation
✓
KPI card showing value and variance
A KPI card showing value and variance is the most appropriate visualization for executive dashboards displaying high-level KPIs such as current revenue, profit margin, and customer count. KPI cards present a single, clear metric with its current value and comparison to a target or previous period (variance), enabling executives to quickly assess performance. This format avoids the clutter of charts and focuses attention on the key number.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Pie chart
Why it's wrong here
A pie chart encodes parts of a whole, so it suits composition such as revenue by region, not a single current value. Plotting one KPI as a pie slice is meaningless. A single-value card or KPI tile displays the current number prominently, which is what an executive dashboard requires.
- ✗
Sparkline for each KPI
Why it's wrong here
A sparkline shows a trend across many time points in minimal space, so it conveys direction rather than the current value the dashboard must display. Sparklines suit embedding historical movement beside a headline figure. A KPI card presents the current number directly, matching the requirement.
- ✓
KPI card showing value and variance
Why this is correct
A KPI card displays a single aggregated value with its variance against target, giving executives immediate status without requiring interpretation of axes or trends. This satisfies the requirement for high-level revenue, margin and customer-count indicators on a dashboard.
- ✗
Gauge chart
Why it's wrong here
A gauge chart shows one value against a target range on a dial, consuming substantial space for a single number and implying thresholds that revenue, margin and customer count lack. Gauges suit capacity or utilisation against a limit. A KPI card states the current value compactly and comparably.
