This example renders a static smiley face using React and SVG, with a yellow circular face, two eyes, and a partially drawn mouth. The code defines the SVG shapes directly in the JSX markup, using explicit `cx`, `cy`, `r`, and `stroke` attributes for the circle elements. It imports React and ReactDOM, and mounts a simple `<App />` component into the `#root` div, while the embedded YouTube video in the README demonstrates the intended interactivity. The visualization relies on React’s declarative component structure to produce the final SVG output.
