This line chart displays one week of temperature data in San Francisco, showing how temperatures fluctuate over time. The visualization uses D3 v5 to render an SVG with a time-scaled x-axis and linear y-axis, with a smooth curve produced by `curveBasis`. The data is loaded via `csv()` from a Data Canvas dataset, and features axis labels, tick marks, and a title. The chart's maroon line path and styled text elements are defined in a separate CSS file.
