Smiley Face-I
A static SVG smiley face appears on a yellow circle with a black outline, centered in a 960×500 viewport. The page loads React 17 and ReactDOM from a CDN, while the main `index.js` file defines a React component that renders a simple "Hello My world!" heading. However, the visible face is drawn directly in the HTML using an SVG `<circle>` element, not through React. The example demonstrates a minimal setup where HTML, SVG, and React coexist in a single page, with the actual smiley shape relying purely on static SVG markup.
