The SWANA Geography Lab
A region is not merely found on a map. It is built from choices about which physical, cultural, historical, and economic connections matter.
Who belongs in the region?
Turn the four lenses on and off. A country brightens when it matches any selected lens. Watch the edges shift—and notice that no single combination produces the one eternally “correct” region.
What makes a chokepoint powerful?
Move the slider to reduce shipping through the Strait of Hormuz. This is an illustrative systems model, not a price forecast. Its lesson is geographic: concentrated routes transmit disruption far beyond the narrow waterway.
100% of normal traffic
At normal flow, the route is still strategically important because so much energy trade is concentrated in one narrow passage.
Model assumption: effects rise nonlinearly because ships, ports, pipelines, insurers, and buyers cannot all adjust at once. The meters show relative pressure only.
Diffusion detective
Read the evidence, then identify the process. You will get an explanation immediately—because the useful part is not the score but the reasoning.
