Fork of Hello HTML
A yellow smiley face is drawn on an SVG canvas. The code defines a React component that renders two eyes and a mouth, with the face's background circle built as a reusable React sub-component. The mouth is created using D3's `arc` function to generate an SVG path with specified radii and angles. The example demonstrates combining React for component structure with D3 utilities for geometry, all rendered into a static SVG graphic.
