{"version":"1.0","type":"rich","title":"MULTILINE MELTED","description":"This visualization shows population trends for world regions from 1950 to 2100, with each line representing a continent and colored using a categorical scale. The chart uses a time-based x-axis and a linear y-axis for population, with the legend ordered by each line’s final value. Built with d3.scaleTime, d3.scaleLinear, and d3.line, the data is melted from UN population estimates and medium-variant projections, then rendered as SVG paths with a basis curve.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4fef87a4f4414e7e890de5ab1bb22b57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
