Live API coding for fame
This example demonstrates the process of live-coding an API data exploration workflow, fetching parking location data from the RDW opendata endpoint and inspecting its structure. It retrieves the JSON response, extracts values from selected columns like `areaid` and `usageid` using JavaScript array methods, and logs unique values to the console. The code also counts occurrences of empty strings within the `areaid` field, showcasing basic data quality checks. It relies on the browser’s native `fetch` API and plain JavaScript functions for filtering, deduplication, and counting, with no external visualization libraries involved.
