{"version":"1.0","type":"rich","title":"CPSC 436V Week 7 - Melting Data for Multiple Lines","description":"This visualization shows global population trends over time for major world regions, with each region drawn as a distinct colored line using a basis curve. The chart orders the color legend by each line’s final population value, and employs D3’s `nest` and `scaleOrdinal` with `schemeCategory10` to group and color the data. It loads UN population estimates from 1950 to 2014, merging them with medium-variant projections through 2100, and renders via SVG with custom axes and a standalone `colorLegend` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ad8d905d0584bba8b4c69f08a4edee4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
