This interactive map of the Netherlands displays provincial boundaries, which users can click to zoom and highlight in red, with a click on the background resetting the view. Built with D3 v6 and TopoJSON, it uses `d3.geoPath` and a Mercator projection to render the shapes, while `d3.zoom` handles panning and scaling between 1x and 8x. The data loads from a remote TopoJSON file via `fetch`, and transitions animate the zoom and fill changes. Hover effects turn regions orange, and SVG elements are used for all rendering.
