DA0-002 Visualization and Reporting Practice Question
A marketing team wants a single view comparing this quarter's campaign performance against the same quarter last year across five channels, with the ability to drill from channel totals down to individual campaign rows. Which visualization structure best supports both the comparison and the drill path?
⚠ Common exam trap
The trap here is choosing a chart that shows magnitude or composition when the requirement is a precise period-over-period comparison combined with hierarchical drill-down.

Correct answer & explanation
✓
A matrix with channels as rows and the two quarters as columns, configured with a drill-down hierarchy from channel to campaign.
A matrix handles both demands at once: channels as rows give a stable axis for comparing the two quarter columns side by side, and the built-in row hierarchy lets a user expand a channel to reveal its campaigns. The comparison stays in one visual while the drill path descends the same hierarchy, avoiding a jump to a separate page.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A treemap sized by campaign spend with channels as top-level rectangles.
Why it's wrong here
A treemap encodes magnitude by area, which is poor for precise quarter-over-quarter comparison because area judgments are less accurate than aligned positions. It also has no column structure to hold two comparable periods, so last year's values would have to be shown some other way. The campaign-level rectangles exist, but they serve composition, not the requested comparison and drill.
- ✓
A matrix with channels as rows and the two quarters as columns, configured with a drill-down hierarchy from channel to campaign.
Why this is correct
A matrix aligns each channel on a row and places this quarter and last year side by side as columns, so the comparison is read horizontally in one glance. Because matrices support hierarchical row groups, expanding a channel row reveals its individual campaigns, delivering the drill path without leaving the visual. One artifact satisfies both the comparison and the drill requirement.
- ✗
A bar chart of this quarter's channel totals with a separate bar chart of last year's totals placed beside it.
Why it's wrong here
Two side-by-side charts force readers to visually shuttle between canvases to compare each channel, which slows the year-over-year judgment the team actually needs. It also provides no drill path, so moving from a channel total to its underlying campaigns would require a separate report page or manual filtering. The structure solves neither requirement cleanly.
- ✗
A line chart plotting campaign rows over time with one line per channel.
Why it's wrong here
Plotting individual campaigns as lines over time answers a within-quarter trend question, not a quarter-versus-quarter comparison by channel. With five channels and many campaigns the lines overlap into an unreadable tangle, and there is no natural hierarchy to drill through. The chart also displaces the year-over-year framing that the request centers on.
