This visualization displays hourly temperature readings for San Francisco over a week, with a smooth line chart tracking the fluctuations across time. The SVG rendering uses D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` for the smoothed path. Data is loaded from a CSV file via `csv`, with timestamps parsed as dates and temperatures converted to numbers before plotting.
