This example demonstrates the D3 general update pattern through a bowl of fruit visualization. It shows five colored circles representing apples and lemons, which appear via a staggered enter transition, shrink and disappear when eaten, and change color and size when one fruit transforms from an apple to a lemon. The code uses d3.scaleOrdinal for color and radius mapping, and applies chained transitions with d3.transition to smoothly animate circle updates. Data joins are handled through selection.data with a key function, merging enter and update selections, and removing exit selections after an animation.
