{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors the world’s countries by economic classification using a spectral color scale, with country names and values shown on hover. The visualization also places a set of fixed coordinates as small circles on the map, though these are filled with the same color scale. Built with D3.js, it projects geographic data from a TopoJSON world atlas using the Natural Earth projection (`d3.geoNaturalEarth1`) and renders paths via `d3.geoPath`. Interactive zooming is enabled through a `d3.zoom` event, which transforms the SVG group containing the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6edae86544094e588ad4e6b9c7fa07d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
