{"version":"1.0","type":"rich","title":"Area Chart (CO₂ vs GDP-sorted Countries, 2025)","description":"This area chart displays CO₂ emissions across countries sorted by GDP per capita for 2025, using a monotone-curved blue fill. The visualization loads CSV data from a GitHub gist via `d3.csv`, then applies `d3.scalePoint` for the categorical x-axis and `d3.scaleLinear` for the y-axis. The `d3.area()` generator with `curveMonotoneX` renders the shaded region, while SVG axes with rotated country labels handle the presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/833a4929a925438fabd4c839c27265dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
