This fork of Hello HTML displays two black-outlined circles on a yellow background, rendered as SVG, alongside a React-generated "Hello JSX" heading. A static SVG circle and two additional circles are hardcoded in the HTML, while React's `ReactDOM.render` mounts the heading into a `#root` div. It uses React 18.1 and ReactDOM 17.0.2 from unpkg, with rendering split between raw SVG markup and the React JSX component.
