Hello HTML!
This example demonstrates a minimal React application rendered alongside hand-coded SVG graphics, producing a static yellow smiley face with two eyes on a 960×500 canvas. The page loads React 18 and ReactDOM from a CDN, then uses `ReactDOM.render()` to mount a simple `<h1>Hello JSX</h1>` component into a `#root` div. The SVG elements are written directly in the HTML body, avoiding any data binding or interaction, while CSS resets the body margins and hides overflow. The visualization combines raw SVG drawing with React’s declarative component model.
