Fork of Line Chart with Multiple Lines
This line chart visualizes a week of temperature data from cities worldwide, sourced from Data Canvas - Sense Your City. The chart uses D3 v5 to render multiple smoothed lines, one per city, with a color-coded legend. It employs `scaleTime` and `scaleLinear` for axes, `nest` to group data by city, and `curveBasis` for line smoothing. The SVG rendering includes a title, axis labels, and a custom color legend, with city lines sorted by their final temperature values.
