Region Hierarchy

How to read this chart

1. 1 The tree is the ancestry. A repeater carries every tag on the path from west down to its own region — read left to right.
2. 2 The rails on the right are the overlaps. Each column is one tag that is also carried by regions living in other branches — the cross-border communities.
3. 3 Click anything — a region, or a rail — to see the exact tag list it ends up carrying.
