This choropleth map visualizes population density across Dutch neighborhoods using a TopoJSON of administrative boundaries. Each polygon is filled according to its population density, with colors highlighting the spatial distribution of inhabitants per area. The view is rendered as an SVG, and an animated transition gradually reveals or recolors the map to emphasize density differences across regions. The dataset encodes each neighborhood's boundary geometry as arcs, which are transformed into a visual hierarchy of density through sequential updates, creating a clear, interactive overview of population concentration in the Netherlands.
