{"version":"1.0","type":"rich","title":"Fork of Keeling Curve","description":"This example reproduces the Keeling Curve, visualizing monthly average atmospheric CO₂ concentrations from 1958 onward, with a clear upward trend. The line chart uses `d3.line`, `scaleTime`, and `scaleLinear` to map dates and concentrations, while `d3.timeParse` converts year-month strings into JavaScript `Date` objects. Data comes from NOAA’s Global Monitoring Laboratory, loaded from a CSV and rendered with SVG paths and custom axes. The chart highlights the seasonal zigzag pattern superimposed on the long-term rise in carbon dioxide.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1578c4639ba84fdcbc259a7a9990e716?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
