This example demonstrates the nested general update pattern for animated transitions in D3.js, using a row of fruit shapes that change over time. Circles and labels are bound to a dataset of apples and lemons, with enter, update, and exit selections handled separately. The code uses `scaleOrdinal` for color and radius, `transition().duration()` for smooth animations, and SVG groups to structure each fruit. Over timed intervals, fruits are removed, replaced, or modified, showing how the nested update pattern manages both parent groups and their child elements independently.
