{"version":"1.0","type":"rich","title":"Line chart with multiple lines","description":"A line chart displays one week of temperature data for multiple cities, with each city represented by a colored line. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map time and temperature, while `nest()` groups the data by city and `line()` with `curveBasis` smooths each series. Color-coded lines are sorted by their final temperature values, and a custom `colorLegend` function renders a categorical legend. The data originates from Data Canvas - Sense Your City, showing temperatures in Celsius.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d97c156678349baae38ad7474062663?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
