This example demonstrates loading and processing JSON data representing car listings, filtering them by price, and formatting them into a plain-text report. It uses JavaScript modules with `export`/`import` statements and Promises to simulate asynchronous data retrieval. The code also includes a separate array of U.S. city data and logs the number of entries to the console. No visualization library is used; the focus is on functional programming patterns with `filter`, `map`, and `join` on arrays, as well as object destructuring.
