Doughnut Economics Radar: Social Floor vs Ecological Ceiling

This simulator renders Kate Raworth's doughnut-economics model as a 2D radial (radar) chart: 12 bars — six social minima and six ecological boundaries — arranged around two reference rings on a single canvas, with a live trend strip underneath. Tune material throughput, resource efficiency, redistribution and population scale and watch each bar respond instantly: social bars that fall short of the inner ring signal a shortfall in human need, ecological bars that push past the outer ring signal a breached planetary boundary. Drag the chart to rotate it and hover any bar for its exact reading, while live counters and a rolling trend line track how many of the 12 dimensions sit inside the safe and just space between the two rings — the same central trade-off of sustainable development, now steerable by hand in flat 2D.
