This example demonstrates a basic React application rendering a static SVG graphic. It shows a large pink circle with purple outlines and two smaller purple circles, accompanied by an “Hello JSX” heading. The code uses React and ReactDOM from CDN, along with JSX syntax in `index.js`. The SVG element is hardcoded in `index.html`, while React renders the header into the `#root` div, and the CSS sets the page margin to zero with hidden overflow.
