This example renders a static text display using React, showing the message "Hello World" inside a `<pre>` element. The code runs entirely in the browser with no data fetching or visualization logic; it simply assigns the message to the DOM node via `document.getElementById`. The page loads a bundled JavaScript file, `bundle.js`, which executes the `index.js` script. No external libraries such as D3 or Three.js are used, and the rendering approach is limited to plain DOM manipulation within an HTML shell.
