{"version":"1.0","type":"rich","title":"US Map","description":"A choropleth map of the United States colors individual states by population, using a threshold color scale that ranges from light yellow to dark amber. The visualization loads US state boundaries from the us-atlas TopoJSON file and renders them as SVG paths via d3.geoPath with an Albers USA projection. Population values are mapped to FIPS codes using a JavaScript Map, and the d3.scaleThreshold assigns fill colors based on population brackets. Hovering over a state triggers a native SVG title tooltip displaying the FIPS code and population figure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7419fbd1d44548bda4064bb69dfe3ba0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
