This example demonstrates the general update pattern for dynamic data visualizations using D3 v5. It shows a bowl of fruit where apples and lemons are rendered as scaled circles with distinct colors, updating as the underlying data array changes. The `fruitBowl` module uses `scaleOrdinal` for color and radius mappings, while D3's selection, merge, and exit methods handle element transitions. The SVG canvas is populated via `select` and `range` to generate the fruit dataset.
