This example shows a smiley face made of overlapping SVG circles inside a React application, with a yellow outer circle for the head and two smaller black circles for the eyes. The code loads React and ReactDOM from a CDN, embeds the face directly in the HTML’s SVG markup, and also runs a React render call using `ReactDOM.render` with the `StrictMode` and `App` components. It relies on static SVG circle elements without any interactive or animated behavior.
