This example demonstrates a minimal web page that combines static SVG graphics with a React application. It renders a yellow smiley face drawn directly in the SVG markup, alongside a React component that outputs "hello jsx" into a separate root div. The page uses React 17 and ReactDOM, included via CDN, to render the JSX element. It also includes inline CSS to reset margins and a console log statement, showing how HTML, CSS, and JavaScript can coexist in a single file.
