This area chart displays San Francisco temperatures over a week, using a smooth curved path to fill the space between the time axis and temperature values. The visualization includes labeled x and y axes with grid lines, and a title, rendered as SVG elements. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and an `area` generator with `curveBasis` to create the shape. Data is loaded from a CSV file containing timestamps and temperature readings, with margins and tick styling configured via CSS.
