{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature readings in degrees Celsius from multiple cities around the world, using data from Data Canvas - Sense Your City. Each city appears as a separate smooth curve, colored via a categorical scale, with a legend positioned to the right. The visualization is built with D3 v5, using `d3.csv` for data loading, `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` with `curveBasis` for path generation, and `d3.nest` to group readings by city. An ordinal color scale assigns distinct hues, and a custom color legend renders circles and labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ca1fd9903eb4177a4ca60b6f1ce2258?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
