This example demonstrates a simple React application that renders a static “Hello React!” message. It initializes a React component using `ReactDOM.render` and displays the text inside a `<div>` element styled with the class `message`. The visualization relies on React 16.13.1 and ReactDOM, loaded via CDN, with the app bundled into `bundle.js`. No additional data sources or interactive features are present, serving as a minimal starter template for integrating React into a visualization gallery.
