This line chart displays one week of temperature readings in degrees Celsius for multiple cities, sourced from Data Canvas - Sense Your City. Each city is represented by a smooth, multi-hued line, with a color-coded legend on the right. The visualization uses D3 version 5, employing `scaleTime` and `scaleLinear` for the axes, `nest` to group data by city, and a Bézier curve for line generation. The chart is rendered as an SVG, featuring a titled y-axis, labeled axes, and a legend created via a custom `colorLegend` module.
