{"version":"1.0","type":"rich","title":"Fork of Melting Data for Multiple Lines","description":"This visualization uses layered line charts to show population trends over time for various global regions, with a legend providing color-coded identification. Built with D3.js v5, the code processes a UN population dataset by melting it from wide to long format, then renders an SVG with time-based x-axis and population y-axis. The graph implements multiple D3 APIs including `scaleTime`, `scaleLinear`, `nest` for grouping, and `line` with `curveBasis` for smoothed paths, while a custom `colorLegend` function displays the categorical color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ab4c8e21f734d11b584df4a860e51a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
