Geography supplies the spatial coordinates.
A subject may be connected to:
a building
a street
a town
a city
a country
a continent
a planet
The scale is flexible.
Coventry Cathedral and Coventry are both geographical references, but they operate at different levels of resolution. England, Britain, Europe and Earth can all describe the same location at progressively wider scales.
That makes Geography especially compatible with Zoom.
We can zoom in from a country to a city, from a city to a building, or even from a building to a particular room.
We can also zoom out.
A link that seems insignificant locally may become much more interesting when placed within a wider geographical network.
Geography also allows movement.
People migrate.
Bands tour.
Aircraft fly.
Goods are shipped.
Ideas spread.
Borders change.
The map itself becomes a network of links.
