This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The smooth curve is rendered using an SVG path generated by d3.line with a curveBasis interpolation. The code employs d3.scaleTime and d3.scaleLinear for axes, with d3.axisBottom and d3.axisLeft creating gridlines and tick labels. The chart includes a title, axis labels, and data-driven styling via CSS, with margins and responsive sizing computed from the SVG dimensions.
