Why the Tube map is genius.
The most famous map in the world is wrong on purpose — and that's the whole point.
In 1931 Harry Beck drew the London Underground like an electrical circuit, not a country. He straightened every line to 0°, 45° or 90°, spaced the stations evenly instead of truly, and kept exactly one real thing: the river. Drag the slider and watch the tangle of real geography resolve into the diagram you can actually use.
Drag geography into a diagram.
Left = roughly where the stations really are. Right = Beck's diagram. Same network, two truths.

45° angles only
Even spacing — not to scale
The Thames — the one truth kept
Colour = the line
Harry Beck, 1931. He drew the Underground like a circuit board and got it rejected for being “too radical” — then it became the template every metro on earth still copies. He kept the river and threw away the rest. Design is deciding what to throw away.
