Three overlapping circles render a simple smiley face on a 960-by-500 SVG canvas. A large yellow circle with a black stroke forms the head, and two smaller black circles create the eyes; the smile is absent, matching the "half way" description. The example runs in a React environment using the `react` and `react-dom` UMD libraries. The SVG markup appears directly in `index.html`, while `index.js` merely imports React and logs the `React` object to the console.
