This area chart visualizes temperature readings over time in Texas, using a smooth, filled curve to highlight the overall trend. The chart employs D3 v6 APIs including `scaleTime`, `scaleLinear`, `area` with `curveBasis`, and SVG rendering via `axisBottom` and `axisLeft`. Data is loaded from a CSV file and parsed into `Date` and numeric values, with a light green fill emphasizing the area beneath the temperature line.
