This example demonstrates a simple text-based report of car listings, filtering a small hardcoded JSON dataset to display only vehicles priced under a given threshold. It shows how modular JavaScript functions can transform and present data as formatted strings in the browser. The code imports car data from a parsed JSON array, applies a filter for maximum price, maps each car through a custom formatter that outputs year, make, model, and price, and joins the results into a readable list. The output is rendered into a `<pre>` element in the HTML page using standard DOM manipulation, with no external visualization libraries.
