Framework playground

Build your own argumentation framework. Click the canvas to add an argument, switch to → Attack and click two nodes to draw an attack between them. The side panel shows grounded / preferred / credulously / skeptically accepted in real time.

What you can try​

  • Recreate Nixon — load the preset, then add a third argument that defends one side. Watch grounded change.
  • Recreate Tweety — use the Tweety preset, then add a meta-argument like "specificity" attacking the bird-fly rule.
  • Build a chain — A attacks B attacks C attacks D. Notice how grounded bounces between odd and even positions.
  • Even cycles vs odd cycles — three nodes in a cycle (A→B→C→A) versus four (A→B→C→D→A). The semantics behave differently.

How it works​

This whole panel is the argumentation Rust crate compiled to WebAssembly. Each click recomputes extensions client-side — no server, no network round-trip. The wasm bundle is around 50 KB; load is a one-time cost on first visit.
