This example renders a static “Hello World” message to the screen using React, displaying the text in a large `<pre>` element. The underlying data comes from a hardcoded JSON array of five used cars, each with year, make, model, and price fields, parsed via `JSON.parse` in the `cars.js` module. The React app accesses the DOM element by ID and sets its text content directly, demonstrating a minimal setup where the visualization data is present but not yet visualized.
