{"version":"1.0","type":"rich","title":"Population time-series","description":"This visualization displays population trends for global regions from 1950 to 2100, using animated line charts that color-code each region via a categorical scale. The data, sourced from UN population estimates, is processed through a custom melt function and rendered as SVG with D3 v5, React, and the `d3.axisBottom`, `d3.axisLeft`, and `d3.line` APIs. A color legend with animated transitions clarifies the mapping, while styled tick lines and labels enhance readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a32b76ec68747cdbd391a484d7534b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
