Line Chart with Multiple Lines
This visualization displays one week of temperature readings for cities worldwide, with each city represented by a smooth, semi-transparent line. The chart uses d3.line with curveBasis to generate paths, d3.scaleTime and d3.scaleLinear for axes, and d3.scaleOrdinal with schemeCategory10 for colors. A custom color legend uses exported functions from colorLegend.js. Data comes from the Data Canvas - Sense Your City dataset, loaded via d3.csv, with nested grouping via d3.nest to separate city series.
