This example shows a static smiley face constructed from three SVG circles: one large yellow circle for the head and two smaller black circles for the eyes. The SVG markup is embedded directly in the HTML, while the linked React code renders only a simple “Hello JSX” heading. The visualization demonstrates a basic geometric composition using SVG primitives with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. React and ReactDOM are loaded from CDN, though the visible face does not depend on React rendering.
