A D3 v6 demonstration shows a bowl of fruit rendered as SVG circles and text labels, with apples and lemons distinguished by color and size via `d3.scaleOrdinal`. The code uses the general update pattern to handle entering, updating, and exiting elements, animating radius changes with `transition().duration()`. Timed `setTimeout` calls remove fruits, change an apple’s type to a lemon, and filter the array, illustrating how data joins update the visualization.
