Logic-Flow Educational Puzzle

Game Concept: An educational game where students link historical events (Chronos) using "Energy Threads." It uses a force-directed layout to keep event bubbles floating naturally in a 3D space.
Technical Prompt:
Create a link-based puzzle. Use a force-simulation logic to prevent bubble overlapping. When two correct bubbles are clicked, draw a CatmullRomCurve3 between them with a glowing neon texture.
