Five fruit circles render as apples in an SVG created with D3 v6. A function called `render` demonstrates the general update pattern by joining data to circles with `selectAll` and `data`, then handling enter, update, and exit selections. The code uses `scaleOrdinal` for color and radius based on fruit type, and `merge` to apply shared attributes. After one second, a fruit is removed; after two, an apple becomes a lemon, showing transitioned states.
