This line chart displays a week of temperature data in San Francisco, with time on the x-axis and degrees Celsius on the y-axis, using data from a remote CSV file. The visualization renders as an SVG, constructed with D3 v5, and employs `scaleTime` for the time-based x-axis and `scaleLinear` for the temperature y-axis. It draws a smoothed line using `line` with `curveBasis`, and adds gridlines and labels via `axisBottom`, `axisLeft`, and explicit text elements. The chart includes a title and axis labels, with points not plotted as circles.
