This interactive D3 v5 visualization demonstrates the general update pattern with SVG rendering, showing a bowl of fruit that changes over time. The code uses `selection.merge()` and key-based data binding to manage enter, update, and exit states, while `d3.scaleOrdinal` maps fruit types to colors and radius values. Mouse events on circles trigger hover highlighting, with the `setSelectedFruit` function updating a selected fruit’s stroke to black. Timed updates pop apples, replace one with a lemon, and filter items, all re-rendering through the reusable `fruitBowl` module.
