{"version":"1.0","type":"rich","title":"CO2 Emissions Over Time","description":"This stacked area chart visualizes global CO2 emissions from 1790 onward, broken down by fossil fuel types—Gas, Liquids, Solids, Cement Production, and Gas Flaring—with total emissions scaled in gigatons per year. The chart uses D3 v4’s `d3.stack` and `d3.area` to render the layers, while `d3-area-label` positions labels within each segment. Hovering over a layer triggers a tooltip showing topic-related words from the cloud.json data, rendered as red text inside a circle. The visualization adapts to window resizing and uses `d3.scaleOrdinal` with `d3.schemeDark2` for color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bea5e42bc2e84e1390b1c5b8d0c7c8f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
