This example shows a yellow smiley face composed of a large circular background, two black eyes, and an arc-shaped mouth, all drawn as react components that render SVG elements. The code defines reusable components for the face’s parts and positions them using absolute pixel coordinates relative to a centered SVG group. It uses d3’s `arc` generator to create the mouth path, while React manages the component hierarchy. The rendering relies on SVG with minimal styling, leaving the face centered on a hidden-overflow page.
