This example demonstrates a simple report generator that fetches car data and displays a filtered list. It uses a `Promise` with `setTimeout` to simulate an asynchronous data request, then applies `filter` and `map` to show cars under a price threshold, formatting each entry with the `formatCar` function. The output is rendered as text into an HTML `<pre>` element via `textContent`. The visualization is minimal, focusing on data transformation logic rather than visual charts, using plain JavaScript with no external libraries.
