How does the dungeon generator work?

The free procedural dungeon generator scatters and separates rooms, finds natural neighbours with Delaunay triangulation, guarantees a connected layout with a minimum spanning tree, adds selected loops for route choice, carves the tile grid, assigns room difficulty, and dresses the result from one replayable seed.
