This visualization displays temperature readings across multiple global cities over a one-week period, using a multi-line chart with smooth curves to emphasize comparative trends. Each city receives a distinct color, identified through a legend positioned to the right of the plot. The implementation relies on D3 v5's scaling, axis, and line generator APIs, with data parsed from a CSV source. The rendering uses SVG paths with semi-transparent strokes and a curve-basis interpolation. The chart sorts cities by their final temperature values, adding a subtle comparative layer to the visualization.
