This chart displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. The data is loaded from a CSV file and rendered as a filled area chart using a smooth curve. The visualization uses D3 v6’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` with the `curveBasis` generator, all drawn as SVG elements with custom grid lines and labels.
