{"version":"1.0","type":"rich","title":"D3 - StreamGraph","description":"A streamgraph displays CO2 emissions for Afghanistan, Albania, Algeria, and Angola from 1970 to 1979, using stacked areas that flow across a time axis. Each colored band represents a country’s emissions, with a tooltip revealing the country name on hover and a legend mapping colors to names. Built with D3 v7, the visualization uses `d3.stack` to compute the stacked series, `d3.area` to generate the path geometry, and `d3.scaleLinear` for axes. Data is loaded from a CSV file via `d3.csv`, and the SVG rendering includes axis labels for Year and CO2 Emissions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7c4e10854894f5abcf010c4b7b20486?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
