This interactive D3.js area chart visualizes temperature trends over 150 days using a synthetic `climate_data.csv` file. The chart displays a light green filled area with a green stroke line, mapping temperature values across the x-axis for "Day" and y-axis for "Temperature." The implementation uses D3.js v7 scale functions (`d3.scaleLinear`) and area generator (`d3.area`) to construct the path, with axes added via `d3.axisBottom` and `d3.axisLeft`. The SVG rendering includes labeled axes and a clean white background, providing a clear view of temperature fluctuations over time.
