This area chart visualizes global average temperatures from 2000 to 2024, showing a steady upward trend from 14.3°C to 15.6°C. The visualization loads data from a CSV file using d3.csv, then employs d3.area and d3.curveMonotoneX to render a smooth filled region with steelblue stroke. Axes are generated with d3.axisBottom and d3.axisLeft, while d3.scaleLinear maps years and temperature values. The SVG chart includes labeled axes and a title, all styled through a separate CSS file.
