Fork of Line Chart with Multiple Lines
A fork of a line chart displays one week of temperature data for cities worldwide, sourced from the Data Canvas - Sense Your City dataset. The visualization uses d3.scaleTime and d3.scaleLinear axes with a d3.line generator and curveBasis to draw smooth paths, colored by city via d3.scaleOrdinal. A custom colorLegend component renders the categorical legend. The SVG is rendered with d3.nest to group data by city, and axes include tick marks and labels.
