This example demonstrates the general update pattern for smoothly transitioning data changes in an SVG visualization. A bowl of fruit, rendered as colored circles, adapts to eating apples and replacing one apple with a lemon through animated position and radius adjustments. The code uses D3 v5’s data joins with key functions, `transition().duration()` for animations, and `scaleOrdinal` for mapping fruit types to colors and sizes. Entering circles fade in from radius zero, while exiting circles shrink away.
