DA0-002 Visualization and Reporting Practice Question
A marketing manager wants to visualize the conversion rate at each stage of a sales funnel, from leads to closed deals. The data shows the number of prospects at each stage. Which chart type is most appropriate for this pipeline analysis?
⚠ Common exam trap
The trap is confusing funnel charts with waterfall charts, as both show progression, but waterfall is for cumulative financial effects, while funnel is for stage-wise reduction in a process.

Correct answer & explanation
✓
Funnel chart
A funnel chart is specifically designed to show the progressive reduction of data as it moves through stages, making it ideal for visualizing conversion rates in a sales pipeline. It displays the number of prospects at each stage, with the width of each section representing the quantity, clearly illustrating drop-offs.
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 rectangle area, so it cannot show sequential stage-to-stage conversion across a funnel. It is tempting because treemaps do display proportions of a total, which would be the right choice for showing category share of overall prospects.
- ✗
Waterfall chart
Why it's wrong here
A waterfall chart shows how an initial value is incrementally increased or decreased by positive and negative contributions, not the count remaining at each sequential funnel stage. It is tempting because waterfalls do model cumulative change, which would be correct for explaining what drove a net change in a metric.
- ✓
Funnel chart
Why this is correct
A funnel chart plots sequential stages as progressively narrowing bars, so the declining prospect count from leads to closed deals is shown directly. This satisfies the pipeline analysis requirement to visualise conversion rate at each sales-funnel stage.
- ✗
Stacked bar chart
Why it's wrong here
A stacked bar chart splits each bar into component categories, so it compares composition within a category rather than the sequential drop-off between funnel stages. It is tempting because stacked bars do show parts of a whole, which would be correct for comparing sub-segment breakdowns across groups.
