{"version":"1.0","type":"rich","title":"Global Tons of CO2 Emissions V2","description":"This visualization shows global CO2 emissions on a world map from 1850 to 2023, using color intensity to represent emission levels. A slider enables year selection, while a rectangular legend maps the green-to-red gradient to millions of tons. The map is rendered with React and D3, using `d3.geoNaturalEarth1` and `d3.geoPath` for geographic projection. Emission data comes from a CSV file, and the color scale applies a fifth-root transformation to visually differentiate lower values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1c2ea9d9b074138bd66e1169080c5bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
