It uses D3 v5 to render an SVG visualization, with the `scaleTime` and `scaleLinear` functions mapping timestamps and temperatures to axes. The chart includes multiple smoothed lines (`line` with `curveBasis`) colored by city via a `scaleOrdinal` color scale, a legend built with a custom `colorLegend` function, and grid lines generated by `axisBottom` and `axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/712b5da1ba964377a4af91f1735534ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
