This line chart displays one week of temperature data in degrees Celsius for cities worldwide, sourced from Data Canvas – Sense Your City. Multiple colored lines represent different cities, sorted by their final temperature values, with a color legend identifying each series. The visualization uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal to map time, temperature, and city categories, while d3.line with curveBasis generates smooth paths. Axes are rendered via d3.axisBottom and d3.axisLeft, with d3.nest grouping the data by city.
