This scatter plot displays daily mean temperatures for San Francisco over time, using a blue area chart to visualize temperature fluctuations. The data is loaded from a CSV file and rendered as an SVG. The visualization uses D3 v5 APIs such as `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` to construct the chart, with `curveBasis` smoothing the area path. While circle elements for individual data points are commented out, the area chart effectively demonstrates the temperature trend across the seasons.
