Bowl of Fruit - General Update Pattern Special Cases
This example demonstrates the "general update pattern" in D3.js, showing how a data visualization animates changes to a dataset of apples and lemons over time. It displays a bowl of fruit, where each fruit is a circle with a type-specific color and radius, and items are added, removed, or modified as the simulation progresses. The code uses D3's selectors and transition methods, including `selection.selectAll`, `.merge()`, and `.transition().duration()`, to smoothly animate enter, update, and exit states. The visualization is rendered as SVG with animations triggered by `setTimeout` calls, which alter the fruit array and re-render the scene.
