This fork of a line chart displays one week of temperature data in Celsius for various global cities, sourced from Data Canvas - Sense Your City. The visualization encodes time on the x-axis and temperature on the y-axis, with each city represented by a colored line using d3.curveBasis for smoothing. It employs d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal with the schemeCategory10 palette, drawing axes via d3.axisBottom and d3.axisLeft. A custom colorLegend function renders the categorical legend, while the SVG rendering includes styled grid lines and titles.
