This example displays a static smiley face drawn with overlapping SVG circles: a large yellow head, two smaller black eye circles, and a curved mouth implied by a dashed path. The face is centered on an 960×500 canvas, with stroke styling on the head for emphasis. The code uses React and ReactDOM to render a placeholder "Hello JSX" heading, while the actual face markup is hardcoded in the HTML alongside the bundled React libraries. The visualization does not include interactive behavior or data-driven updates.
