Travelling Salesman on a Flat Earth

Text on the meme

If the earth isn't flat how come the travelling salesman problem looks like this and not like this?

What it means

A diagram of the travelling salesman problem shows five numbered nodes connected by lines with distance labels, followed by a tangled spherical network of colorful lines. The joke compares the clean, flat graph representation with a chaotic shape that supposedly resembles a non-flat Earth, playfully using flat-Earth logic. It is sent as a nerdy absurdist reaction about geometry, graphs, and confusing visualizations.
