This visualization displays a week of temperature data for San Francisco as a smooth line chart, with time on the x-axis and temperature on the y-axis. The SVG is rendered using D3 v5, with scales and axes generated via `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`. The line is drawn using `d3.line` with `curveBasis` for smoothing. Data is loaded from a CSV file using `d3.csv`, and the chart includes a tilted y-axis label and a title.
