This line chart displays one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with time on the x-axis and degrees Celsius on the y-axis. The visualization uses a filled area chart with a basis curve to smooth the temperature readings, rendered as an SVG. Built with D3 v5, it applies scaleTime and scaleLinear for axis scaling, axisBottom and axisLeft for tick marks, and the area generator with curveBasis to create the shaded region. Circular data points are styled via CSS, while grid lines and axis labels are positioned using explicit margins.
