This example demonstrates how D3.js can create a smiling face with animated, moving eyebrows. It shows fundamental DOM manipulation by using `d3.select`, `d3.range`, and `d3.scaleOrdinal` to bind and update data-driven SVG elements. The `fruitBowl` function manages enter, update, and exit selections with `transition().duration()` for smooth changes, while the eyebrow animation is driven by JavaScript `setTimeout` calls that modify the fruit array and re-render.
