A row of apples animates through enter, update, and exit states as fruits are eaten and replaced by a lemon. The visualization demonstrates D3's general update pattern, using keyed data joins and transition delays to morph circle radii and fill colors over one-second intervals. The code employs d3.scaleOrdinal for color and size mapping, with selection.merge and exit transitions, all rendered as SVG circles in a static bowl-like arrangement.
