This example demonstrates the simplest possible setup for a visualization with React, rendering the text “Hello World” to the page. It uses a plain HTML file with a `<pre>` element and a separate JavaScript file. The `index.js` file selects that element using `document.getElementById` and sets its `textContent` property to the message. The project includes a `bundle.js` script, indicating a build step, and serves as a minimal starting point for more complex React-based visualizations.
