This area chart displays one week of temperature in degrees Celsius in San Francisco, sourced from Data Canvas - Sense Your City. The visualization uses D3 v5 to map time and temperature data to SVG paths, with a curved area generator filling the space beneath the line. Axes are rendered using d3.axisBottom and d3.axisLeft, while the chart is scaled with d3.scaleTime and d3.scaleLinear. The code applies a basis curve for smooth transitions between data points.
