This example demonstrates a minimal React application that renders the text “Hello React” into a web page. The code imports React and ReactDOM, defines a simple `App` component returning a `<div>`, and uses `ReactDOM.render` to mount it into the `#root` element. The page includes production builds of React and ReactDOM from unpkg, with basic body styling and a hidden overflow, serving as a foundational starter template rather than a data-driven visualization.
