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 a time-scaled x-axis and linear y-axis to plot temperature fluctuations, with a smooth curve generated via d3.line and curveBasis. The code employs d3.csv for data loading, d3.scaleTime and d3.scaleLinear for scales, and d3.axisBottom and d3.axisLeft for tick marks, all rendered as SVG elements within a fixed 960×500 viewport.
