{"version":"1.0","type":"rich","title":"MULTILINE MELTED","description":"This chart displays projected population trends for world regions from 1950 to 2100, with each region shown as a distinct colored line. It uses D3.js v5 to load CSV data, melt it into a tidy format, and render an SVG line chart with a time-scaled x-axis and linear y-axis. The color legend is ordered by each line’s final population value, using D3’s `nest` and `descending` functions. The data originates from UN population estimates and medium-variant projections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/da01d5346bc345cbb5d7b747b50e3dab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
