This visualization displays a line chart of San Francisco temperatures over a week, with time on the x-axis and temperature on the y-axis. The SVG chart is built using D3 v5, employing `scaleTime`, `scaleLinear`, and `line` with `curveBasis` for smooth interpolation. Axis labels and a title are added via SVG text elements, while grid lines are generated using tick sizes. Data is loaded asynchronously from a CSV file using `csv`, with timestamps parsed as `Date` objects and temperatures converted to numbers.
