{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays temperature readings from multiple cities over one week, with each city represented by a distinct colored line and a corresponding color legend. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map time, temperature, and city categories, while `nest()` groups the data by city and `line()` with `curveBasis` generates smooth paths. Axes are rendered with `axisBottom` and `axisLeft`, and the legend is built using a custom function that appends circles and text. Data originates from the Data Canvas - Sense Your City dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2e83cabd38a42388b904a355c4038b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
