This interactive map of the Netherlands highlights individual municipalities, rendered as SVG paths and colored dark with light strokes. The visualization uses `d3.geoPath` with a Mercator projection, and `d3.zoom` enables panning and zooming. Clicking a municipality triggers a smooth transition that fills the selected region in red and zooms in on its bounds. The geographic data comes from a TopoJSON file fetched from Cartomap, and the map animates using D3 transitions.
