This example demonstrates the general update pattern in D3.js using a bowl of fruit visualized as SVG circles and text labels. It shows three special cases: removing the last item, updating an existing item’s properties, and filtering out a middle element. The code uses d3.scaleOrdinal for color and radius mapping, selection.enter(), .merge(), and .exit() to handle joins, with a rect drawn to represent the bowl. A timed sequence of setTimeout calls triggers each state change.
