This line chart displays a week of temperature data from multiple cities, with each city represented by a distinct colored line over time. The visualization includes axes with labels, a legend showing city names, and a title. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `scaleOrdinal`, `nest` to group data by city, and a `line` generator with `curveBasis` for smooth paths. Data comes from Data Canvas - Sense Your City, rendered as SVG with custom axis styling and a color legend component.
