This example shows a simple, static smiley face built with React and rendered as an SVG graphic. It uses `ReactDOM.render` to mount the component, with circles and lines defining the face’s features, including a red head, white eye highlights, black eyebrows, and a nose. The code relies on React’s JSX syntax and the SVG `<circle>` and `<line>` elements to create the composition. No interactive behavior or data-driven features are present; it is purely a fixed visual output.
