{"version":"1.0","type":"rich","title":"Fork of US Cities Map At Night","description":"This fork of the US Cities Map At Night visualization renders a dark-themed United States map with a graticule overlay, using d3.geoAlbersUsa and d3.geoPath to project state boundaries from a TopoJSON atlas. It plots over a thousand cities as small glowing dots with low opacity, pulling latitude, longitude, and population data from a CSV. The loading sequence fetches the atlas and city data asynchronously, then draws the map and points in a single SVG using D3’s data join pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5ac0345318348b6a7b11353f4ab8e86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
