This example demonstrates the general update pattern for handling dynamic data changes in D3.js v5, showing how SVG elements are added, removed, and modified in response to a sequence of timed events on a bowl of fruit. The visualization starts with five apples, then removes one, changes one apple into a lemon, and removes another apple, all while using `selection.selectAll`, `.enter()`, `.merge()`, and `.exit()` to manage the lifecycle of `g` groups containing circles and text labels. The code applies `scaleOrdinal` for both color and radius scales, mapping fruit types to specific visual properties, and uses `setTimeout` to trigger each update transaction.
