This interactive map of Dutch municipalities uses D3.js and TopoJSON to display the 2020 administrative boundaries. Users can click any municipality to zoom in and highlight it in red, while hovering turns regions orange. The visualization implements pan and zoom controls via d3.zoom, with smooth transitions between zoom levels. Geographic projections are handled with d3.geoMercator and d3.geoPath, loading data from a remote TopoJSON source. The SVG-based rendering includes dynamic stroke scaling to maintain consistent border visibility during zoom operations.
