This line chart displays one week of temperature data in degrees Celsius for San Francisco, sourced from Data Canvas - Sense Your City. The visualization uses d3.csv to load the data, d3.scaleTime and d3.scaleLinear for the axes, and d3.line with curveBasis to render a smooth path in SVG. Axis labels, a title, and gridlines are included via d3.axisLeft and d3.axisBottom, with margins applied to the chart group.
