This line chart visualizes a week of temperature readings in San Francisco, plotting temperature against time. The data is loaded from a CSV file and rendered as a smooth curve using d3.line with curveBasis. Axes are generated with d3.axisBottom and d3.axisLeft, while scales employ d3.scaleTime and d3.scaleLinear. The SVG output includes grid lines, axis labels, and a title, with styling applied via CSS classes like .line-path and .axis-label.
