Each city appears as a distinct colored line, sorted by final temperature. The visualization uses d3.line with curveBasis for smoothing, d3.scaleTime and d3.scaleLinear for axes, and d3.nest to group data by city. A custom colorLegend function renders the categorical color scale, while axis labels and a title contextualize the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/210cda95cb6c41c9a88e657d633e4f90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
