{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows an interactive map of New York cities and towns that zooms into a selected region on click, highlighting the active area in sky blue while fading other boundaries. Built with D3 v3, it uses `d3.geo.albersUsa` for projection, `d3.geo.path` for rendering TopoJSON features, and a `g.transition` with scaling and translation to animate the view. State and town borders are drawn as SVG paths, with click handling on both the background and individual regions to toggle zoom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03d91f07aab14168b11c02065a6f92c9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
