An analyst wants to show how the component pieces of a company's business units contribute to the company's overall revenue. Which of the following should the analyst use to best demonstrate this breakdown?
→ A Sankey diagram is ideal for illustrating flow-based relationships, such as how different units or sources contribute to a total. It's especially effective for showing proportions, hierarchy, and decomposition — such as revenue contribution by business units.
Why the other options are incorrect:
A: Box plots show distributions and spread — not contributions or breakdowns.
C: Scatter plot matrix explores relationships between numeric variables, not part-to-whole relationships.
D: Residual charts are diagnostic tools for regression — not for revenue visualization.
