This example demonstrates the general update pattern in D3, showing how data joins handle adding, removing, and modifying elements in a visualization. A bowl of apples and lemons is rendered as SVG circles that transition between states as fruits are eaten or replaced over timed intervals. The code uses `d3.scaleOrdinal` for color and radius mapping, and calls `fruitBowl` as a reusable function that leverages `selection.enter()`, `selection.merge()`, and `selection.exit()` with `transition.attr` for smooth animations. The data consists of generated fruit objects with random IDs, visualized in a fixed SVG canvas.
