2015-2100 Population Data
This visualization presents global population dynamics from 2015 to 2100 using an animated population pyramid. The chart displays age structure (0-19 years) on the vertical axis and population counts on the horizontal axis, with male and female data rendered as two back-to-back horizontal bar series. The animation steps through each year, updating the bars to reflect changing age distributions over time. The design uses a muted color palette to distinguish sexes, with male and female data shown on opposite sides of the central axis. The SVG rendering in D3.v3 creates a smooth, continuously updating transition that allows viewers to observe demographic shifts across the 85-year period at a glance.
