{"version":"1.0","type":"rich","title":"Centered US Choropleths Map","description":"A centered US choropleth map displays state boundaries with a uniform purple fill, using state-level rate data from a TSV file. The visualization loads US Atlas TopoJSON data and renders it with React and D3 v5, using `d3.geoAlbers` for projection and `d3.geoPath` to draw state and interior mesh paths. The code includes commented-out attempts at threshold-based color mapping with `d3.scaleThreshold` and `d3.schemeGreens`, though the final version applies a single color to all states.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/025a9aae536c4a3e807211ef1f364fab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
