{"version":"1.0","type":"rich","title":"Fork of Melting Data for Multiple Lines","description":"This example visualizes population over time by region from a UN dataset, showing multiple lines from 1950 to 2100 using nested data. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` for axes and color, with `axisBottom` and `axisLeft` for tick marks. Lines are generated via `line` with `curveBasis`, and a custom `colorLegend` function displays the categorical color scale. The code employs `nest` and `descending` to sort regions by their final population value, rendering the SVG with a multiply blend mode.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bee8300c78642748dfbc94ffef545c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
