This example demonstrates animated transitions of fruit shapes in an SVG bowl using D3 v5. Circles representing apples and lemons enter, update, and exit with sequential timing, showing how data joins and key functions track object identity. The code uses `d3.scaleOrdinal` for color and radius mappings, `d3.selectAll` and `selection.merge` for enter-update handling, and `transition.duration` to animate circle positions and radii over one second. Fruits are stored as an array with random IDs, and `setTimeout` triggers state changes like removing or replacing items.
