{"version":"1.0","type":"rich","title":"Choroplet map","description":"This choropleth map colors countries by economy category, using a spectral color scale to visually distinguish different economic classifications. The visualization renders geographic boundaries with `d3.geoPath` and a `geoNaturalEarth1` projection, while loading country data from a CSV file and TopoJSON world atlas. Users can zoom interactively via `d3.zoom`. A custom color legend, built with SVG circles and labels, shows the mapping between categories and colors, with hover states highlighting individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45e134af93a84c22a8de9e9886d754b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
