{"version":"1.0","type":"rich","title":"Activity7.1_Question2","description":"This visualization displays global CO₂ emissions over time as a green area chart, with the x-axis representing report years and the y-axis showing carbon output. The area chart is rendered using D3.js v7’s `d3.area()` generator, which fills the space between the line and the baseline. Data is loaded asynchronously via `d3.csv()` from a GitHub Gist, then mapped to linear scales (`d3.scaleLinear`) for positioning. Axes are added with `d3.axisBottom` and `d3.axisLeft`, and the SVG output is styled with a simple external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81870ac7741744d8842af02c62ae9a94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
