This example demonstrates the general update pattern for handling special cases in data changes. It shows a bowl of fruit where five apples are initially displayed, with each fruit represented by a circle and a text label. The code uses d3’s `scaleOrdinal` for color and radius mappings, and the `selectAll`/`merge`/`exit` pattern to manage SVG elements. The rendering uses d3.v5 with SVG output, and the data source is hardcoded as a series of apple objects.
