Testing Temperature in San Francisco Line Chart
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.
