Show HN: Constellations – On-the-fly D3 collaboration graphs of history via LLMs (github.com)

A new project called Constellations has emerged, utilizing dynamic AI-powered knowledge graphs to trace historical collaborations between notable figures through events and projects. Instead of relying on a pre-computed database, Constellations generates its graphs on-the-fly using local neighborhood explorations initiated by user-selected nodes, such as films or historical events. This innovative approach allows users to visualize intricate networks, revealing connections like the route from John von Neumann to Geoffrey Hinton while sidestepping common pitfalls of flat LLM queries. The significance of Constellations lies in its unique structure that treats people as nodes and events as hubs, thus avoiding the "hallucinated friendships" that often plague AI-generated content. Built with a custom D3.js layout for graphical representation and leveraging live queries through Gemini Pro, the project demonstrates a successful integration of LLMs with practical AI development methodologies. By caching data in a PostgreSQL database for efficiency and leveraging tools like React and Tailwind CSS for its frontend, Constellations exemplifies the evolving capabilities of AI in creating interactive and relevant historical narratives.
