This example demonstrates D3.js general update patterns by rendering a bowl of fruit as colored circles that change over time. The visualization shows apples and lemons entering, exiting, and updating their position, size, and color through staggered transitions. Using the `data` join with key functions and `merge`, the code animates SVG circles via `transition().duration()`, applying `scaleOrdinal` color and radius scales based on fruit type. The data source is a JavaScript array modified with `setTimeout` calls to simulate eating and replacing fruit.
