{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data for multiple cities around the world, sourced from Data Canvas - Sense Your City. The visualization uses D3 v5 to render an SVG with a time-based x-axis and linear y-axis. Cities are color-coded via the `scaleOrdinal` and `schemeCategory10` APIs, with a custom legend built from `colorLegend`. The `nest` function groups data by city, while `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` generate the smoothed paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ce6bd70c9ab4a7495ffa19dee98bb7b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
