Line Chart with Multiple Lines
This line chart displays one week of temperature data in degrees Celsius for cities worldwide, sourced from Data Canvas - Sense Your City. The visualization uses multiple colored lines, one per city, sorted by final temperature, with a color legend positioned to the right. It renders as an SVG using D3 v5, employing d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.line with curveBasis, d3.nest, and d3.axisBottom/axisLeft. Grid lines and axis labels clarify the time and temperature scales.
