This line chart visualizes one week of temperature data in degrees Celsius for San Francisco, sourced from Data Canvas: Sense Your City. The visualization plots temperature against time, with a smooth curve connecting data points and labeled axes for both variables. The chart is rendered as SVG using D3 v6, employing d3.csv for data loading, d3.scaleTime and d3.scaleLinear for scaling, d3.axisLeft and d3.axisBottom for axes, and d3.line with curveBasis for the smoothing.
