This visualization shows global monthly land temperatures from 1750 to the present using an SVG line chart. The primary series, LandAverageTemperature, is plotted across time with a smooth path, revealing seasonal cycles and long-term warming trends. Uncertainty is conveyed through a subtle band drawn from the LandAverageTemperatureUncertainty values, and the chart is built with D3 v4 to map the CSV data to scales and axes. Missing values are skipped, allowing the line to continue across gaps in the record. The MIT-licensed example is implemented in pure SVG, providing a clean, minimal look at over 250 years of climate data.
