This example renders a static smiley face using SVG primitives within a React 17 application. It shows a large yellow circle with a black stroke as the face, two smaller filled circles as eyes, and no mouth, created directly in the markup. The visualization uses SVG elements like `circle` for shapes and relies on the UMD build of React for setup, though no React-specific features are demonstrated. The drawing is hard-coded at 960 by 500 pixels with CSS hiding page overflow.
