This example demonstrates the general update pattern in D3 with special cases for enter, update, and exit selections. It shows a bowl of fruit where apples are added, removed, and replaced with lemons over time using `setTimeout` calls. The visualization renders SVG circles and text labels for each fruit, with colors and radii mapped via `scaleOrdinal`. The code uses D3 v5 selections, `.merge()` for combining enter and update groups, `.exit().remove()` for deletions, and dynamic data binding to track state changes across transitions.
