This example demonstrates the general update pattern in D3.js, showing how a bowl of fruit changes as apples are eaten or transformed into lemons over time. A sequence of timed events triggers data updates, and the visualization transitions between three scenarios: removing an apple, changing one apple to a lemon, and filtering out another apple. The code uses D3 v5 with `selectAll` and `data` joins to handle enter, update, and exit selections, plus `scaleOrdinal` for color and radius mappings. SVG circles and text elements render each fruit based on its type.
