testing Keeling Curve
✓ Published0🌍 Public
This visualization reproduces the Keeling Curve, plotting average monthly atmospheric CO₂ concentration from 1958 to the present. The line chart displays the characteristic upward and seasonal sawtooth pattern of carbon dioxide measurements. The visualization uses D3 v7's `d3.line` for the path, `d3.scaleTime` for the time axis, and `d3.timeParse` to convert year and month strings into JavaScript `Date` objects. Data comes from NOAA's Global Monitoring Laboratory, loaded from a CSV file.
