This example demonstrates the general update pattern for animated transitions in D3.js. As the data changes over time, the visualization shows a row of fruit shapes that are added, removed, or altered—apples appear, one is eaten, another becomes a lemon, and an apple is removed from the middle. The code uses D3’s selection `.enter()`, `.merge()`, and `.exit()` methods to handle the incremental updates to SVG circles and text labels. It applies ordinal color and radius scales to style apples and lemons distinctly.
