{"version":"1.0","type":"rich","title":"Fork of Melting Data for Multiple Lines5","description":"This visualization displays population trends over time (1950-2100) for various regions, with each line colored by region name and sorted by final population value. It uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `scaleOrdinal`, `nest`, `line` with `curveBasis`, and `axisLeft`/`axisBottom` to render axes. Data is loaded from UN population estimates via `csv` and processed through a custom `melt` function. The chart includes a color legend, axis labels, and uses SVG for rendering, with lines styled using mix-blend-mode multiply.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/413f0844f59c4c56a60a064ab3ff6bc8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
