This example displays a static text message, "bonjour," in large type within an HTML page. It demonstrates a minimal use of D3.js, loading the library via a CDN link, while the primary logic resides in JavaScript files. The `index.js` file imports an array of car objects from `cars.js` but currently only assigns a hardcoded string to the page's message element, ignoring the dataset. The code uses standard DOM manipulation to set the text content of a `<pre>` element.
