{"version":"1.0","type":"rich","title":"State Map with Population","description":"This choropleth map visualizes U.S. state populations, filling each state with a blue color scale from light to dark based on its population value. It uses d3.geoAlbersUsa for projection and d3.geoPath to render TopoJSON state and nation outlines from the us-atlas dataset. Population data is loaded from a separate text file and parsed into a lookup table, with tooltips appearing on hover. The visualization is built with D3 v7 and rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95427306d4b247fe91ed2b9597a3b496?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
