{"version":"1.0","type":"rich","title":"CO2 Emissions Over Time","description":"A stacked area chart visualizes global CO2 emissions from 1790 onward, broken down into five categories: Gas, Liquids, Solids, Cement Production, and Gas Flaring, measured in gigatons per year. The chart uses `d3.stack` to aggregate the series and `d3.area` with `d3.curveBasis` for smooth rendering as SVG paths. Labels are positioned automatically via `d3-area-label`, while axes and color encoding rely on `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.schemeDark2`. Data comes from a CSV file loaded with `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/020db47cc32144e192fa6f0f7eeb1cf7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
