This line chart visualizes a week of temperature data in San Francisco, with time on the x-axis and temperature on the y-axis. The visualization uses SVG rendering with D3 v5, employing scales like `scaleTime` and `scaleLinear`, along with `axisBottom` and `axisLeft` for the axes. The line is drawn using D3’s `line` generator with a basis curve to smooth the path. Data comes from a CSV file loaded via `csv`, and the chart includes labeled axes and a title.
