Users can hover over the chart to select a specific year, which triggers a vertical line to appear and updates the visualization accordingly. The chart is built using D3 v5, with the data sourced from UN population estimates. It employs D3’s `scaleTime`, `scaleLinear`, and `nest` functions to manage the time axis, population values, and multiple region groups, rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f7487f64c854c9f94a6abcb98455255?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
