A dynamic fruit bowl visualization demonstrates SVG shape updates and color transitions using D3's data join pattern. Apples and lemons appear as circles with distinct fill colors and radius values, driven by ordinal scales for both color and size. The code uses `selection.enter`, `.merge`, and `.exit` methods with `transition().duration()` to animate circles entering, updating, and leaving as fruits are added, removed, or changed. JavaScript `setTimeout` calls trigger sequential data mutations, showing how D3 v5 handles animated updates to SVG elements.
