Five fruits (plums and lemons) are rendered as colored circles in an SVG, demonstrating D3's general update pattern for entering, updating, and exiting elements. The code uses `d3.scaleOrdinal` for color and radius mapping, and `d3.select` with data joins. Each transition animates circle radius and x-position over one second, with exiting circles shrinking to zero before removal. The example uses d3.v5 and follows a modular structure with the `fruitBowl.js` function handling the update logic.
