Fork of Line Chart with Multiple Lines
This visualization shows a week of temperature readings across multiple global cities, using smooth curved lines to compare trends over time and a color legend to distinguish each city. The data comes from Data Canvas - Sense Your City, plotted on an SVG canvas with D3 v7. It uses `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal` with `schemeCategory10`, and `d3.line` with `curveBasis` to generate the paths. Axes are rendered with `d3.axisLeft` and `d3.axisBottom`, while a custom `colorLegend` function maps city names to colors.
