This visualization charts temperature over time for a week in San Francisco, using an area graph filled in maroon against a plain coordinate grid. The chart displays time on the x-axis and temperature on the y-axis, with labeled axes and a title. Built with D3 v7, the code employs `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` with `curveBasis` to render the smooth area. The data is loaded from a remote CSV file featuring temperature and timestamp columns.
