This area chart displays temperature measurements in San Francisco over a week, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 to load CSV data, scales time and linear values with `scaleTime` and `scaleLinear`, and renders the area path using the `area` generator with a `curveBasis` interpolation. Axis labels and a title are added via SVG text elements, while grid lines are drawn through tick marks. The chart applies a maroon fill with a red stroke to the area path, and includes axis labels for “Time” and “Temperature”.
