Smiley face part I
This example shows a yellow smiley face drawn as a static SVG graphic, with two black eye circles positioned symmetrically on a larger yellow face circle. The face is rendered using React components that return SVG elements, with hardcoded dimensions for the viewport, eye offsets, and radii. The code uses React’s `ReactDOM.render` to mount the component tree, and constructs the circles via inline JSX attributes like `cx`, `cy`, and `r` within a single `<svg>` element. No dynamic data or interaction is present—only fixed visual primitives.
