The visualization uses D3 v7 and TopoJSON to load and render state boundaries via `d3.geoPath` with an Albers USA projection. A sequential blue color scale maps cost index values, while an interactive tooltip div appears on mouseover to show state-specific data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4258356ca14e4e0690ad54dbd8c26fe5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
