This line chart visualizes one week of temperature data in San Francisco, showing temperature in degrees Celsius over time. The chart uses D3 v5’s `scaleTime` and `scaleLinear` to map timestamps and temperatures, with axes generated by `axisBottom` and `axisLeft`. Curved lines are drawn using `line` with `curveBasis`. Data is loaded via `csv` from a remote dataset and rendered as an SVG.
