A fruit bowl demonstrates the General Update Pattern for data joins. Apples and lemons enter, update, and exit with smooth transitions, changing shape, color, or position. The example uses d3-selection’s `data()`, `enter()`, `merge()`, and `exit()` methods, with `transition().duration()` animating circle radii and fills. A d3.scaleOrdinal maps fruit types to colors and sizes, while an SVG rect forms the bowl.
