This interactive map visualizes where parking facilities are located relative to city centers across the Netherlands, with buttons to filter parking spots for Amsterdam, Den Haag, Rotterdam, and Utrecht. The visualization uses d3.geoMercator and d3.geoPath to project Dutch township boundaries from TopoJSON, while parking locations are fetched from the RDW Open Data API, cleaned, and drawn as blue circles around a red city center marker. The code relies on d3.select, d3.json, d3.zoom, and TopoJSON's feature extraction, with SVG rendering and transition-based animations for zoom resets.
