A row of apples and lemons animates through the general update pattern in this D3.js example. Buttons and timed re-renders trigger enter, update, and exit selections as fruits are added, replaced, or removed. Using the `selection.join()` method with d3.v5, the code binds fruit data to SVG groups, transitioning circle radii, colors, and text labels between states. The `colorScale` and `radiusScale` ordinal scales map fruit types to visual properties.
