This example demonstrates the general update pattern in D3.js by animating a bowl of fruit over time. It shows five circles representing apples and lemons, which are added, removed, or changed in type via timed intervals. The code uses D3 v5 with SVG rendering, `scaleOrdinal` for color and radius mapping, and explicit enter, update, and exit selections. The `fruitBowl` function merges enter and update selections to manage circles and text labels dynamically.
