{"version":"1.0","type":"rich","title":"map us 1","description":"This map of the United States displays cities as red circles, overlaid on a gray state map. It uses D3’s `geoAlbersUsa` projection and `geoPath` to render the states, and plots city coordinates from `citydata.csv`. Clicking a city draws black lines to all other cities, with line thickness proportional to the clicked city’s `flow` value, and hover transitions enlarge and recolor the selected circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
