Smiley Face 1
This example shows a yellow smiley face rendered as three circles: a large head and two smaller eyes. Purely static and hand-coded, it uses raw SVG elements placed inside an `index.html` file. The React code in `index.js` imports React and ReactDOM but renders only an empty JSX heading, leaving the face untouched. The head circle is filled yellow with a black stroke, while the eye circles use the default black fill, creating a minimal, unfinished appearance.
