{"version":"1.0","type":"rich","title":"ICE8_US_States_Population","description":"This choropleth map displays U.S. state populations, with darker blue fills indicating higher population values and gray for states without data. It uses D3 v7 with `d3.geoAlbersUsa` projection, `d3.geoPath` for rendering, and `topojson.feature` to parse the us-atlas states-10m TopoJSON source. A `d3.scaleSequential` with `d3.interpolateBlues` maps population values to colors, while mouseover events update an HTML tooltip showing state names and population in millions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e956d1ff365340af80473fd13db8a80f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
