{"version":"1.0","type":"rich","title":"Fork of Streamgraph","description":"This fork of a streamgraph visualizes global CO2 emissions over time as a stacked area chart. Segments representing fossil fuel types—Solids, Liquids, Gas, plus Cement Production and Gas Flaring—are stacked and colored via a D3 ordinal scale. Hovering highlights a single area. The chart uses the `d3.stack`, `d3.area`, and `d3.curveBasis` APIs, with labels positioned by the `d3-area-label` library. Data comes from a remote CSV file, parsed into gigatons, and rendered as SVG using D3 v4.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6faa350134f94c13926d12c730472276?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
