Animating a bowl of fruit, this example demonstrates D3’s enter, update, and exit pattern on SVG circles. Apples and lemons, distinguished by red and yellow fills, shrink and expand their radii over one-second transitions as items are removed, replaced, or changed. The code uses `d3.scaleOrdinal` for color and size, `selection.data` with an id accessor, and chained `transition().attr` calls to morph circle properties.
