population graph
This visualization presents United Nations population projections for countries with over one million people, using stacked areas to show the changing composition of global population from 2010 to 2100 under the medium fertility variant. The chart displays several projection scenarios as colored layers, with buttons that reorder the stack using different `d3.stack` order functions (ascending, descending, inside-out, reverse) and offset methods (wiggle, silhouette, expand). Built with D3 v4, the visualization loads CSV data and renders animated transitions between stacking arrangements.
