This example demonstrates the general update pattern in D3 v5, showing how data joins manage enter, update, and exit selections for a simple fruit bowl visualization. Circles represent apples and lemons, with colors and radii mapped via ordinal scales. Using D3 selections and the `merge()` method, the code updates the SVG as fruits are removed, replaced, and filtered over timed intervals. The `fruitBowl.js` module exports a function that binds fruit data to circle elements, while `index.js` drives the state changes with `setTimeout`.
