This area chart displays San Francisco's weekly temperature variations in degrees Celsius, using data from the Data Canvas - Sense Your City project. The visualization employs a smooth curved area path generated with d3.area and curveBasis, mapping time on the x-axis and temperature on the y-axis. It renders as SVG using D3 v5, with scales from d3.scaleTime and d3.scaleLinear, and axes configured via d3.axisBottom and d3.axisLeft. The chart includes labeled axes and a title, with data loaded asynchronously from a CSV file.
