Smiley face Part 1
This example shows a simple smiley face drawn with static SVG circles on a yellow head, including two eyes and a mouth, using React and ReactDOM for the page structure. The SVG is embedded directly in the HTML, with explicit coordinates and styling for the face elements. The code loads React 18.2.0 from a CDN and renders a basic “Hello JSX” heading into the root div, while the smiley face itself sits outside the React-managed area in the raw markup.
