Fork of Keeling Curve
This visualization reproduces the Keeling Curve, plotting the monthly average atmospheric CO₂ concentration measured at Mauna Loa from 1958 onward. It shows the well-known upward trend with seasonal oscillations. The D3.js code loads data from a CSV file provided by NOAA’s Global Monitoring Laboratory. It uses `d3.line` to generate the path, `d3.scaleTime` for the x-axis, and `d3.timeParse` to convert the year and month strings into JavaScript `Date` objects.
