{"version":"1.0","type":"rich","title":"Fork of NYC Borough map","description":"A responsive world map renders country boundaries from a TopoJSON file fetched from the visionscarto-world-atlas package, converted to GeoJSON via `feature` from `topojson-client`. The React app manages viewport-size state and passes the data to a separate `viz` module, which builds the visualization using `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule`. Countries fill with a light gray and white strokes overlaid on a graticule grid and outline, all rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/66929dc59445495cb1c33f42f8f0a673?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
