This area chart visualizes one week of temperature data in San Francisco, showing temperature in degrees Celsius over time. The chart displays a smooth, filled area path with axis labels and a title, rendered as an SVG using D3 v5. It employs `d3.scaleTime` and `d3.scaleLinear` for scaling, `d3.area` with `curveBasis` for the shape, and `d3.axisLeft` and `d3.axisBottom` for axes. Data is loaded from a CSV via `d3.csv`, with timestamps parsed into Date objects.
