{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays U.S. state-level data with interactive filtering, allowing users to select a category and see the corresponding color shading update across the map. The visualization uses D3 v5 and TopoJSON to render the geographic boundaries via `d3.geoPath`, while a color legend component updates dynamically based on the selected filter. State polygons are drawn in an SVG container, and the filtering logic re-applies a color scale to the shapes. The map loads and processes CSV data with a custom utility, and styling is defined in a separate CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c62e1162161c4b15b305ec215a6b511e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
