This example demonstrates a minimal React application that renders a simple text message, “Helo React,” into a web page. It uses React 16.9.0 and ReactDOM to mount a functional component into a root HTML element, with the page styled to hide margins and overflow. The code loads React and React-DOM from unpkg CDN links and serves as a basic starter template for building React-based visualizations, though no data or graphical output is present beyond the static text. The main logic in `index.js` defines an `App` component and calls `ReactDOM.render` to place it in the DOM.
