This interactive visualization displays global temperature anomalies from 1880 to 2020, with data relative to the 20th-century average. Users can toggle between line and area chart views, adjust line smoothing with d3.curveLinear, curveMonotoneX, or curveBasis, and filter by decade through a button panel. Hover tooltips reveal year-specific values, while a statistics sidebar calculates trends, volatility, and range using linear regression. The visualization uses D3.js v7 scales and axes within a React framework, with data loaded from a CSV file.
