{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This visualization displays temperature readings from multiple cities over a one-week period, with each city represented by a distinct colored line. The chart uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for smooth paths, and `nest` to group data by city. A custom `colorLegend` component renders ordinal color categories, while axis labels and a title annotate the SVG output. The data is loaded from a CSV hosted on VizHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6c29e9fc4934bc984d0ec166ab66914?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
