This line chart visualizes a week of temperature measurements in San Francisco, plotting timestamps along the x-axis against temperature values on the y-axis. The visualization uses d3.scaleTime and d3.scaleLinear to map the data, with d3.axisBottom and d3.axisLeft rendering the labeled axes. A smooth line is generated using d3.line with the curveBasis interpolation, and the data is loaded asynchronously from a CSV file using d3.csv. The SVG output includes axis labels, a title, and styled grid lines.
