This area chart depicts temperature readings over time in San Francisco, using a smooth curve to trace the trend across the dataset. Rendered as an SVG, the visualization employs D3 v5 APIs like `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` with `curveBasis` to generate the filled path. Grid lines and axis labels clarify the timestamp and temperature values, while styling comes from a linked CSS file. The data is loaded via D3’s `csv` method from a remote dataset.
