This example demonstrates the D3 general update pattern using animated circles to represent a bowl of fruit. Apples and lemons appear as red and yellow circles of different radii, with items entering, exiting, and updating their type over time. The React-based implementation uses D3 v5’s `selectAll`, `.data()`, `.enter()`, `.merge()`, and `.exit()` methods alongside `.transition()` to smoothly animate position and size changes, driven by `Math.random()` IDs and a simple `range()` dataset.
