This line chart displays one week of temperature in degrees Celsius for San Francisco, using data from the Data Canvas - Sense Your City project. The visualization plots temperature over time with a smooth curve, rendered as an SVG. The code employs D3 v5 APIs including `d3.csv` for loading the dataset, `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for tick marks, and `d3.line` with `curveBasis` for the path. Axis labels and a title are appended as text elements.
