This example visualizes parking data special days, showing the fetched dataset of parking locations and a count of occurrences for a selected special day. The workflow fetches data asynchronously from the RDW Open Data API using the `fetch` function and JSON-parsing via `response.json()`. It then applies custom filtering and counting functions from the Sorteren module, which use `map` and `forEach`, respectively, to process the data. The results are logged to the console with `console.log`, and the page is styled with a large font-size via CSS.
