This example demonstrates D3's general update pattern by showing a bowl of fruit that changes over time. Apples and lemons render as SVG circles with distinct colors and radii via `scaleOrdinal` color and radius scales. The `fruitBowl` function binds fruit data to circle and text elements, using `enter`, `merge`, and `exit` selections to handle additions, updates, and removals. Timed `setTimeout` callbacks trigger transitions by eating apples, replacing one with a lemon, and filtering data.
