This area chart visualizes dry-air temperature readings over time, using a smoothed curve to connect daily temperature points across a date range in October and November 2021. The visualization displays the temperature trend with a filled maroon area beneath the curve, while circular markers indicate individual data points. The chart includes labeled axes for date and temperature in degrees Celsius, with a title describing the relationship. The code uses d3.csv to load the dataset, d3.scaleTime and d3.scaleLinear for scaling, and d3.area with curveBasis to generate the filled path.
