This is a map of the 435 districts that the USA is split into for the purposes of voting for members of Congress the powerful people who pick the policies the President can pass.
Because elections have to be fair, it's important that the map is fair.
That's why every ten years the boundaries get redrawn to make sure every district always contains, as closely as possible the same number of people, about 700,000.
Which means that this map is actually a very handy way of glancing at population density across the United States.
For example, sparsely populated Wyoming has just one district and just one representatitive. And densely populated New York has 26.
That makes sense. But if you zoom in, some of it doesn't make sense. Lots of districts have very suspicious looking shapes. Buh? Guh? Fnuhh?
Do districts really have to be so fnuuh just to get the populations equal? Nope!
There's something more sinister going on. And to find out what it is, we have to go back to 1812. Where are we? We're still in England But it's 1812.
Shouldn't we be in Boston? The story starts in Boston In the office of the Governor of Massachusetts, Elbridge Gerry - with a "guh"? - with a "guh".
There was an election coming up and it looked like Gerry was about to lose his job.
