{"version":"1.0","type":"rich","title":"Keeling Curve","description":"This visualization displays the Keeling Curve, showing monthly average atmospheric CO₂ concentration from Mauna Loa from 1958 onward. The line chart reveals both the seasonal oscillations and the steady upward trend in carbon dioxide levels over time. It uses D3 v7’s `scaleTime`, `scaleLinear`, and `line` generators for the chart, with custom axis and label functions. Data is loaded from a CSV file, parsed with `csvParse`, and dates are converted using `timeParse` before being rendered as an SVG path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9377132631854a89867b50639b45a7cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
