{"version":"1.0","type":"rich","title":"usapopulation_map","description":"This choropleth map of the United States visualizes estimated 2020 state populations in millions, using a blue sequential color scale to encode values. Built with D3 v7 and the TopoJSON library, it projects state boundaries with an Albers USA projection through `d3.geoPath`. The map reads population data from a hardcoded JavaScript object and renders an interactive SVG where hovering over a state displays its name and population in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3783a9560f04b7a8e7ab73d273e4299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
