This example demonstrates the D3 general update pattern with special cases, animating a bowl of fruit where apples and lemons are added, removed, and substituted over time. It shows how to handle entering, updating, and exiting SVG elements using `selection.enter()`, `selection.merge()`, and `selection.exit()`. The code uses `d3.scaleOrdinal` for color and radius mapping, and SVG `circle` and `text` elements rendered within groups, with data-driven transforms positioning each fruit.
