A bowl of fruit demonstrates animated updates to a D3 data join. Apples and lemons are drawn as circles using `d3.scaleOrdinal` for color and size, with fruits entering, exiting, and changing type over time. The code uses `selection.data`, `merge`, and `transition` to smoothly move, resize, and remove circles. D3 v6 is loaded from a CDN, and the visualization runs on an SVG in a minimal HTML page.
