Move the mouse over the grid or map to see the migration volumes. The gridded view shows an overview of all global flows. Each large square represents a country, placed approximately in its geographical position. Within each large square, an identical world grid map is displayed. The darker green cells represent higher flows.
To zoom in to the grid, drag with the left mouse button; to pan, drag with the right button; the R key resets a zoomed view.
To toggle between in-migration and out-migration, press the O key.
