Correct answer: Pie chart
Pie charts show part-to-whole proportions and work best with only a few categories.
Question 2: In Tableau, what does a dual-axis chart allow you to do?
- Overlay two measures on the same axis space (Correct answer)
- Split a worksheet into two dashboards
- Create two separate data sources

Question 3: Which feature ensures two axes in a dual-axis chart share the same scale?
- Synchronize Axis (Correct answer)
- Edit Alias

Correct answer: Synchronize Axis
Right-clicking the secondary axis and choosing Synchronize Axis aligns both scales.
Question 4: What is the primary purpose of a heat map in Tableau?
- Show intensity of values using color across a matrix (Correct answer)
- Display geographic boundaries

Heat maps use color intensity to reveal density or magnitude across two dimensions.
Question 5: Which mark type would you choose to create a highlight table in Tableau?
- Square (Correct answer)
- Line

- Tooltip card
Correct answer: Columns or Rows shelf
Dimensions placed on Columns or Rows define the discrete categories shown as bars.

- A treemap
- A bullet graph
Correct answer: A line/time-series trend
Continuous dates on Columns generate a continuous axis ideal for time-series lines.
