This example displays a static text message, "Hello world !!", on a webpage with a large font size. It demonstrates a minimal setup for building a data-driven report using the VizHub platform. The code imports a hardcoded array of car records from a separate module, parses the JSON with `JSON.parse`, and then uses the DOM API `document.getElementById` to inject the message into a `<pre>` element. The data source is included directly in the `cars.js` file, though it is not currently visualized or referenced in the output.
