Reading the chart

What this example shows

  • North–South is the heaviest corridor, and the two directions nearly balance out.
  • West sends consistently more people than it receives from every partner — net outflow across the board.
  • Arc size around the rim reflects each region total across all its flows, so the busiest regions take the most circumference.
