This line chart shows one week of temperature data (in degrees Celsius) in San Francisco, sourced from Data Canvas - Sense Your City. It uses d3.scaleTime and d3.scaleLinear for the axes, d3.axisBottom and d3.axisLeft for tick rendering, and d3.line with curveBasis to draw a smooth path. The SVG chart includes gridlines via tickSize, axis labels, and a title, with data loaded asynchronously via d3.csv.
