Documentation

fjadra is a library for simulating physical forces on particles, which was heavily inspired by d3-force. Its main use case is to layout graphs (i.e. node-link diagrams)—if you are looking for a pure physics engine, you might want to check out the excellent Rapier and Parry from Dimforge.

Development is sponsored by Rerun, a startup building
an SDK for visualizing streams of multimodal data.

• Produce outputs that are comparable to d3-force.
• Lightweight with only minimal dependencies to allow wasm-bindgen and future no_std support.
• Idiomatic Rust API that still follows the d3 conventions where possible.
• Performance that allows user interactions.

We currently support the following forces:

• Collision on circles (Collide)
• Centering (Center)
• Springs (Link)
• Charge and repulsion (ManyBody)
• Gravity (PositionX and PositionY)
