This line chart displays dry air temperature (T) against date over time from the provided CSV dataset, with each data point marked as a blue circle connected by a steelblue line. The visualization uses D3 v5’s `scaleTime` and `scaleLinear` for the date and temperature axes, along with `axisBottom` and `axisLeft` to render gridlines and tick labels. Chart title and axis labels are added as SVG text elements, while the data is loaded via `csv()` and parsed into JavaScript `Date` objects before rendering.
