This example demonstrates the general update pattern in D3, where data joins manage the entering, updating, and exiting of SVG circles that represent fruits in a bowl. It shows three sequential transitions: removing an apple, changing an apple to a lemon, and filtering out another apple. The code uses `selection.data()`, `.enter()`, `.merge()`, and `.exit()` within a custom `fruitBowl` function, applying ordinal scales for fruit color and radius. A `setTimeout` chain triggers each update, making the pattern of data-driven DOM changes explicit.
