Color-coded circles represent fruits in a static SVG bowl, with steelblue apples and an orange lemon positioned along a row. The example demonstrates a data join pattern, updating the visualization when fruits are removed or one apple changes to a lemon. Using d3 v5, it employs `scaleOrdinal` for color and radius mappings, and selection methods like `merge` and `exit` to handle dynamic data changes. The fruits are generated in code, not from an external dataset.
