This is a great library. I especially appreciate that they added a version for Svelte (with specific examples for Svelte 5).

It's very convenient how you create the graph, with nodes just being Svelte components. Adding custom edges isn't very hard either.

If you're curious what you can do with it, I made this demo for myself https://youtu.be/aVY7ySPiSo8 (never launched it). I used Svelte Flow to visualize AI doing research, my first project using LLMs.
