Lean 4 is an open-source theorem prover and programming language, developed by Leonardo de Moura at Microsoft Research, designed for writing and verifying formal mathematical proofs with deterministic correctness.

Two-hop subgraph: this entity, every entity it directly relates to, and every entity those neighbors relate to. Drag a node, scroll to zoom, click to inspect — or click any neighbor and re-center the atlas there.

How to read this: the white-ringed node is Lean 4. Surrounding nodes are direct relationships; the second ring is what those neighbors connect to. Edge thickness scales with source-article evidence. Click any node and choose Center graph here to walk the graph.
