This example demonstrates the general update pattern for data joins in D3.js, showing how fruit elements enter, update, and exit within an animated SVG bowl. Apples and lemons are rendered as colored circles with labels, transitioning smoothly as fruits are removed or replaced over timed intervals. The code uses D3 v5 selections with `data()`, `enter()`, `merge()`, and `exit()` to manage DOM elements, employing `scaleOrdinal` for color and radius mapping and `transition().duration()` for animations.
