This example shows a simple smiley face drawn as three purple and black SVG circles: one large circle for the face and two smaller ones for the eyes. The code uses React 18.2.0 and renders directly to an SVG element with fixed `cx`, `cy`, and `r` attributes, along with explicit `fill`, `stroke`, and `stroke-width` properties. The page loads React via a UMD script and logs the React object to the console, but no interactive behavior or data binding is implemented.
