This example demonstrates the D3 general update pattern by animating a row of fruit-shaped circles as apples are added, removed, or changed into lemons over timed intervals. The visualization uses SVG circles with ordinal color and radius scales, and relies on D3 version 6’s `selection.data`, `enter`/`exit` selections, and `transition` to smoothly update position, size, and color over one-second durations. Data is generated client-side with random IDs, and three subsequent updates trigger the transitions.
