This line chart displays one week of temperature data in degrees Celsius for San Francisco, sourced from the Data Canvas project. The visualization uses d3.csv to load the temperature readings and renders them as a smooth line via d3.line with curveBasis. Time is mapped on the x-axis using d3.scaleTime, while temperature is scaled with d3.scaleLinear on the y-axis. Axes are generated with d3.axisBottom and d3.axisLeft, and the SVG output includes styled ticks, labels, and a title.
