This example presents an interactive map of the United States using d3.geo.path with an Albers USA projection, rendering state boundaries as SVG paths. Clicking a state triggers a smooth zoom animation that scales and translates the map to center on the selected region, highlighting it in orange. The map is constructed from topojson.feature and include a mesh overlay for state borders. The zoom effect is achieved by transitioning the group element's transform attribute using d3.transition over 750 milliseconds.
