An interactive choropleth of the Netherlands' 2020 municipalities allows users to click any region, which highlights it in red and smoothly zooms in via a geometric zoom transform. The map renders SVG paths using d3.geoPath with a Mercator projection, while interaction relies on d3.zoom for pan/zoom transitions. Hovering turns a municipality orange. Data comes from a remote TopoJSON file of the `gemeente_2020` boundaries, styled with light gray fills and subtle black strokes.
