This line chart displays one week of temperature data in San Francisco over time. It uses D3 v6 to load the CSV dataset, parse timestamps and temperatures, and render an SVG with scales from `d3.scaleTime` and `d3.scaleLinear`. The chart includes a smoothed path generated by `d3.line` with `curveBasis`, plus labeled axes using `d3.axisBottom` and `d3.axisLeft`. A title and rotated y-axis label clarify the visualization.
