This area chart displays the daily average temperature in January 2024. The visualization combines a smoothed line and a semi-transparent filled area beneath it, with both axes labeled and grid lines provided. Built with D3 v5, the code uses `scaleTime` and `scaleLinear` for scaling, `axisBottom` and `axisLeft` for axes, and `curveBasis` for smoothing the line and area paths. Data is loaded from a remote CSV via `csv()`, and the chart is rendered as SVG.
