This line chart displays one week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The visualization renders as an SVG using D3 v5, employing `scaleTime` and `scaleLinear` for the axes, `line` with `curveBasis` for the smoothed path, and `axisBottom`/`axisLeft` for tick marks. Data is loaded via `csv` from a remote dataset, with timestamps parsed as dates and temperatures converted to numbers. The maroon line is drawn with a stroke width of five, accompanied by styled axis labels and a title.
