This example displays a map of New York counties using an Albers USA projection with D3 v3 and TopoJSON, showing county boundaries and state borders in white. Clicking a county triggers a smooth zoom animation that centers the view on that region, highlighting it in sky blue while scaling stroke widths inversely. The visualization uses `d3.geo.albersUsa`, `d3.geo.path`, and a 750-millisecond transition with the `scale` and `translate` transforms, with data loaded from a GitHub-hosted TopoJSON file.
