This area chart displays temperature readings in San Francisco over a week, using a smooth blue filled path to convey trends across time. The visualization loads CSV data from a public dataset and renders an SVG with D3 v5, employing `scaleTime` and `scaleLinear` for axes, `area` with `curveBasis` for the smooth path, and `axisLeft`/`axisBottom` for labeled gridlines. The chart includes axis labels and a title, with parsing of timestamps and numeric temperature values in the data loading step.
