This line chart displays one week of temperature in degrees Celsius for San Francisco, using data from Data Canvas - Sense Your City. The visualization plots temperature against time, with a smooth curve generated by d3.line and curveBasis. The chart includes labeled axes for Time and Temperature, with a title, and uses d3.scaleTime and d3.scaleLinear for scaling, along with axisBottom and axisLeft for the ticks. The SVG rendering is driven by D3 v5, with styling applied via external CSS for the line, labels, and ticks.
