It helps you understand how each feature contributes to the separation between groups. This analysis reveals which features are most distinctive for each cluster or class. Use Feature Overlay Analysis **after** clustering or classification to understand your results. It is especially useful for identifying which geometric properties (area, perimeter, compactness) differ most between groups. ### Use Cases * **Cluster interpretation**: Understand what makes each cluster unique by comparing feature distributions across groups. * **Feature relevance**: Identify which geometric properties are most useful for distinguishing between categories. * **Result validation**: Verify that clusters represent meaningful differences in the data, not random noise.
