This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It plots temperature in degrees Celsius against time, with a smooth curved line generated using `d3.line` with `curveBasis`. The chart includes labeled axes and a title, rendered as an SVG. The code uses d3 v5 functions including `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and `extent`, with data loaded via `csv` and parsed into dates and numeric temperatures.
