DA0-002 Visualization and Reporting Practice Question
Which chart type is best for showing the sales pipeline from leads to closed deals, illustrating how many prospects drop off at each stage?
⚠ Common exam trap
DA0-002 often tests the confusion between funnel charts and waterfall or stacked bar charts — candidates must recognize that funnel charts specifically depict sequential stage drop-off, while waterfall charts show cumulative positive/negative contributions.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Funnel chart
A funnel chart is designed to show a sequential process where values decrease through stages, making it ideal for visualizing a sales pipeline from leads to closed deals and highlighting drop-off at each stage. Its tapering shape directly communicates conversion and attrition, which is exactly what the question asks for.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Treemap
Why it's wrong here
A treemap encodes hierarchical part-to-whole magnitude by nested rectangle area, so it cannot show sequential stage-to-stage drop-off between pipeline phases. It is tempting because it displays proportional volumes, but it would be correct for comparing category composition within a hierarchy, not funnel progression.
- ✓
Funnel chart
Why this is correct
A funnel chart directly encodes sequential stage attrition, plotting descending bars for each pipeline phase from leads to closed deals. Its tapering shape makes drop-off volume visually explicit at every stage, satisfying the stem's requirement to show how many prospects are lost between stages. Other chart types cannot represent ordered stage reduction as clearly.
- ✗
Waterfall chart
Why it's wrong here
A waterfall chart shows how an initial value is incrementally increased or decreased by discrete contributions, not the count of prospects remaining at each sequential pipeline stage. It is tempting because it depicts stepwise change, but it would be correct for decomposing a financial total into its contributing components.
- ✗
Stacked bar chart
Why it's wrong here
A stacked bar chart shows composition of a total across categories, not the sequential reduction of prospects through ordered pipeline stages. It is tempting because segments can imply decreasing portions, but it would be correct for comparing part-to-whole breakdowns across categories rather than stage-by-stage attrition.
