This area chart displays temperature readings over a week in San Francisco, with data loaded from a CSV file. The visualization uses D3 v5 to render an SVG, employing `scaleTime` and `scaleLinear` for axes, and the `area` generator with `curveBasis` to create a smooth filled path. Individual data points appear as circles, though set to zero opacity, while axis labels, tick marks, and a title are added via `axisBottom` and `axisLeft`.
