This example shows a static SVG scene of a yellow circle with two smaller black circles, rendered alongside a React-generated "Hello JSX" heading. The code combines a hand-written SVG directly in the HTML with a React component mounted via `ReactDOM.render`. It uses the React 17 UMD production builds from unpkg, with the SVG coordinates and styling defined inline, while the React app only produces a simple text element. No data or interaction is present; the visualization demonstrates how to embed SVG markup within a React-powered page.
