DA0-002 Visualization and Reporting Practice Question
A junior data analyst is asked to create a chart that shows total monthly revenue for the past 24 months so the finance team can see whether revenue is generally rising or falling over time. Which chart type is most appropriate?
⚠ Common exam trap
The trap here is treating any chart that includes all the months as valid, even when the chart type cannot express direction of change.

Correct answer & explanation
✓
A line chart with month on the horizontal axis and total revenue on the vertical axis
A line chart is the standard choice for showing change over a continuous, ordered time dimension because the connected line makes direction and rate of change immediately visible. The finance team's question is about trend, not composition or correlation, so a pie chart, stacked bar chart, or scatter plot would obscure the answer. Month on the horizontal axis and revenue on the vertical axis aligns with conventional time-series design.
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 stacked bar chart with one stack per month and a segment for each sales region
Why it's wrong here
A stacked bar chart emphasizes regional composition within each month, not the overall trend. Comparing total bar heights across 24 months is possible but less immediate than a line, and the internal segments distract from the finance team's question. It answers a different question about regional contribution rather than revenue direction.
- ✓
A line chart with month on the horizontal axis and total revenue on the vertical axis
Why this is correct
A line chart connects ordered time points, making the direction and shape of the trend easy to perceive. With 24 monthly values, the line reveals whether revenue is rising, falling, or fluctuating. This directly answers the finance team's question about the overall trend across two years.
- ✗
A pie chart with one slice per month showing each month's share of total revenue
Why it's wrong here
A pie chart with 24 slices is unreadable, and it shows composition rather than trend. The finance team wants to know whether revenue is rising or falling over time, which a pie chart cannot express. Month-to-month change is lost, and the many thin slices make even the composition hard to judge.
- ✗
A scatter plot with month on the horizontal axis and revenue on the vertical axis
Why it's wrong here
A scatter plot is intended to show the relationship between two continuous variables, not an ordered progression. Plotting months as points loses the connective continuity that makes a trend visible, and viewers must mentally link the dots. It is a poor fit for communicating a 24-month revenue trajectory to a finance audience.
