This example renders a simple yellow smiley face using React 17 and SVG. It shows how static SVG shapes can be composed directly within an HTML document, relying on the `svg` element’s default coordinate system. The drawing consists of three circles: a large yellow face with a black stroke, and two smaller black eyes centered at fixed positions. The code uses raw React JavaScript via `unpkg` and the `react.production.min.js` script, with no additional visualization libraries or data processing.
