This example demonstrates the general update pattern in D3.js through a dynamic bowl of fruit. It shows five apples on a bowl-shaped SVG rectangle, then handles special cases: removing the last apple, replacing an apple with a lemon, and filtering out a specific middle apple. The code uses d3.select, data joins with enter/merge/exit, and d3.scaleOrdinal for color and radius mapping. SVG circles and text elements render the fruits, with transitions triggered by setTimeout.
