This example demonstrates D3’s general update pattern for binding data to SVG circles, showing how entering, updating, and exiting elements transition smoothly as fruit data changes over time. A bowl of apples shrinks as fruits are removed, one apple changes into a lemon, and another apple is filtered out, with each state change animated via `transition().duration()`. The code uses `scaleOrdinal` for color and radius mappings, `selection.data()` with a key function on fruit IDs, and explicit `.enter()`, `.merge()`, and `.exit()` chains to manage the circle lifecycle. Rendering targets SVG, driven by `d3.select` and `range` in a vanilla JavaScript setup.
