A Week of Temperature displays temperature readings from multiple cities over a single week using multi-line time series. Colored lines, generated by the `line` generator with `curveBasis` smoothing, show temperature trends, while an ordinal color scale with a custom legend distinguishes cities. The chart employs `scaleTime` and `scaleLinear` for axes, with data loaded via `csv` from a Curran dataset. Gridlines and rotated axis labels clarify temporal and temperature values.
