This line chart shows one week of temperature data for cities around the world, sourced from Data Canvas - Sense Your City. Each city is represented by a smooth curved line, colored via an ordinal scale, with a legend positioned on the right. Built with D3 v5 in SVG, it uses `scaleTime`, `scaleLinear`, `line` with `curveBasis`, `nest` to group data by city, and `axisBottom`/`axisLeft` for axes. The chart sorts cities by their final temperature value, with axis gridlines and a title.
