{"version":"1.0","type":"rich","title":"CO2","description":"This example visualizes global CO2 emissions by country on an equal-Earth projection map. Each country is filled with a blue-to-red linear color scale corresponding to its emissions value, while countries without data appear grey. The visualization loads geographic boundaries from a GeoJSON file and CO2 data from a CSV, then renders two side-by-side SVG maps using D3 v6’s `d3.geoEqualEarth`, `d3.geoPath`, and `d3.scaleLinear`. The code is built with React and uses a `Map` for country lookup during rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5025b436fdb34ce8a91ee97a862e557a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
