This example displays the message "This is not done" centered on a bare HTML page. It uses the React framework, though the core rendering relies on plain HTML and JavaScript. The code imports a `cars` dataset from `cars.js`, which contains five car records with make, model, year, and price fields, but this data is not visualized. The page structure is defined in `index.html`, and `index.js` uses `document.getElementById` to set the text content of a `<pre>` element.
