This example demonstrates the general update pattern in D3.js by animating a bowl of fruit that changes over time. It shows how data joins manage entering, updating, and exiting SVG elements—apples are eaten, one apple turns into a lemon, and positions shift with each render cycle. The code uses d3-scale’s `scaleOrdinal` for color and radius mapping, while transitions animate circle sizes and repositions groups after each state change. Rendered as SVG, the bowl is a static rectangle, and text labels identify each fruit type.
