For a retailer needing to visualize total revenue without drill-down options, which visualization is most suitable?

The most suitable visualization for displaying total revenue without drill-down options is a pie chart. A pie chart effectively represents proportions of a whole, making it intuitive for viewers to grasp how total revenue is distributed across different categories or segments at a glance. Each slice of the pie corresponds to a specific category's contribution to the overall total, which is exactly what a retailer would need to obtain a clear understanding of their revenue distribution.

While the other visualizations may provide valuable insights under different circumstances, they are not optimized for presenting total revenue in a straightforward manner without the option to drill down. A line chart typically shows trends over time, which would not suit the need for a static total. A treemap organizes data hierarchically and is better for demonstrating relationships between variables, which is unnecessary when a simple total is required. Similarly, a scatter plot is designed to show correlations between two variables, rather than displaying a single total figure. The pie chart focuses on the whole versus parts, offering clarity for the retailer's purpose of visualizing total revenue.
