{"version":"1.0","type":"rich","title":"Centered US Choropleths Map","description":"This visualization displays a centered choropleth map of the United States, with each state colored according to a rate value from a TSV data file. The map uses an Albers projection and renders state boundaries, interior meshes, and a graticule. Built with React and D3 v5, the code loads TopoJSON and TSV data via `Promise.all`, then applies a threshold color scale (`d3.scaleThreshold`) with `d3.schemeGreens` to encode the rates. The map data originates from the US Atlas TopoJSON repository.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e0a37ef6f2a94876945b8f753e55f6bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
