Five pieces of fruit sit in a drawn bowl, rendered as SVG circles with labels. The example demonstrates the D3 general update pattern: entering, updating, and exiting selections manage changes to the fruit array over time, as apples are eaten and one apple is replaced by a lemon. The code uses `selection.enter()`, `selection.merge()`, and `selection.exit()` to handle dynamic data, with `d3.scaleOrdinal` mapping fruit types to colors and radii. Updates occur via `setTimeout` calls that modify the fruit data and re-render.
