This line chart visualizes temperature in San Francisco over time, with a smooth curved line connecting data points plotted against a time axis and a linear temperature axis. The visualization uses D3 v6 with SVG rendering, employing `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` with `d3.curveBasis` to generate the path. Data comes from a CSV file loaded via `d3.csv`, parsing timestamps as dates. Axes include gridlines, labels, and a chart title.
