{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature readings from cities worldwide, using data from Data Canvas - Sense Your City. Each city appears as a smooth, semi-transparent colored line that traces temperature changes over time. The visualization includes a color legend, axis labels, and a title. Built with D3 v5, the code uses `d3.line` with `curveBasis`, `d3.nest` for grouping by city, and `d3.scaleTime` and `d3.scaleLinear` for the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ce6b144d00643348e7e7038a1d640ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
