This line chart visualizes one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City project. It displays temperature in degrees Celsius over time, with a smooth curved line connecting data points against a grid with labeled axes. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the chart as SVG. Data is loaded from a CSV file via the `csv` function and rendered inside the SVG canvas.
