This line chart displays one week of temperature data in degrees Celsius for San Francisco, sourced from the Data Canvas - Sense Your City project. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render a smooth path, while gridlines, axis labels, and a title are added via SVG elements. The data is loaded from a CSV file using `csv`, and each timestamp is parsed into a `Date` object before rendering.
