{"version":"1.0","type":"rich","title":"Fork of D3 World Mapzzz","description":"A choropleth map of the United States visualizes a diversity index for each state, ranging from white to blue via a linear color scale. The visualization uses D3 v4 with `d3.geoAlbersUsa` for projection and `d3.geoPath` to render state boundaries from TopoJSON data. State polygons are filled based on a hardcoded dataset of diversity values, and hovering highlights the state with a thicker stroke. The code includes a commented-out tooltip and a legend using `d3.legendColor`, though neither is fully implemented.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcec79f69f994c2fb985b1348ee684b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
