This line chart displays a week of temperature in degrees Celsius for San Francisco, using time-series data from the Data Canvas - Sense Your City project. The visualization renders an SVG with a smooth curved line, showing temperature fluctuations over time. It uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate the path. Grid lines and labeled axes for time and temperature are drawn, while the data is loaded via `csv` from a remote URL.
