This example demonstrates the general update pattern in D3 with special cases for enter, update, and exit selections. It shows a bowl of fruit where apples are eaten, replaced with lemons, and removed at timed intervals, using ordinal scales for color and radius based on fruit type. The code uses `d3.scaleOrdinal`, SVG circle and text elements, and merge operations to handle entering and updating nodes smoothly. Data is static in-memory JavaScript objects, rendered as styled SVG shapes.
