{"version":"1.0","type":"rich","title":"NYC Map","description":"This example visualizes the five boroughs of New York City using a conic equal-area projection. The map displays geographic boundaries as vector paths, with a graticule overlay and an outline for context. It fetches TopoJSON data from a GitHub repository and converts it to GeoJSON using `topojson-client`. The rendering relies on `d3.geoPath` and `d3.geoConicEqualArea` from the D3 library, with SVG elements joined via `selectAll().join()`. The projection parameters are tuned specifically for the city’s latitude and longitude range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0190908ba93b4018a0d02ef44b6a0064?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
