Show HN: Constellations – On-the-fly D3 collaboration graphs of history via LLMs

Update Jan 11:

Originally designed to map world history, Constellations has evolved into a Universal Bipartite Explorer. It uses LLMs to identify the fundamental "Atomic" building blocks and the "Composite" collections that connect them in any domain.

Supported Bipartite Pairs: History: Person (Atomic) ↔ Event/Project (Composite) Cinema: Actor/Director (Atomic) ↔ Movie/TV Show (Composite) Sports: Player (Atomic) ↔ Team (Composite) Culinary: Ingredient (Atomic) ↔ Recipe (Composite) Medicine: Symptom (Atomic) ↔ Disease (Composite) Academia: Researcher (Atomic) ↔ Paper/Grant (Composite)

I built this to see if I could create 'collaboration graphs' on the fly using LLMs instead of a pre-computed database. It connects people to people through events they both participated in.

The project was 100% 'vibe coded'. I started in Google AI Studio, moved to Antigravity, then Cursor, and finally Codex. The README has the full 'tool-hopping' story and the initial prompt that started it all.
