{"version":"1.0","type":"rich","title":"test_d3_multilinechart","description":"This example shows temperature readings from multiple cities over one week, using smooth curved lines to compare trends. The visualization renders as an SVG with D3 v5, using `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` with `curveBasis` for path generation, and `d3.nest` to group data by city. A custom color legend component is imported from a separate module, while data loads from a CSV containing timestamps and temperatures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2807f0e8440c473284f383782417b4f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
