A static smiley face is rendered as a single SVG graphic in a React component. The face is composed of D3-generated arc paths for the mouth, ears, and eye highlights, alongside plain SVG circles, ellipses, lines, and a custom path for hair. The code uses React 17, D3 v7’s `arc` method, and ReactDOM to mount the SVG directly into the page. The drawing is centered in a 960×500 viewport using a translation transform group.
