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 to render an SVG with a time-scaled x-axis and linear temperature y-axis, featuring gridlines and axis labels. Data is loaded from a CSV file and parsed into date and numeric values. The line is drawn using `d3.line` with the `curveBasis` interpolation, while axes are generated with `axisBottom` and `axisLeft` and styled with custom CSS.
