A fork of the "Smiley Face Part II" example renders a static smiley face using React and SVG. The face consists of a yellow circle with a black stroke, two black eye circles, and a mouth drawn as a ring using a D3 arc. The component calculates dimensions from the browser window and positions elements relative to the center. The code uses the React `ReactDOM.render` method and the D3 `arc` API, with the SVG output filling the entire viewport.
