This example demonstrates the general update pattern in D3 by animating a fruit bowl over time. Apples and lemons are drawn as scaled circles, with colors and radii mapped via `scaleOrdinal`. A sequence of timeouts triggers state changes—removing fruits, replacing an apple with a lemon—and re-renders the SVG. The code uses `selection.selectAll`, `.enter()`, `.merge()`, and `.exit()` to handle the incremental updates.
