FeynDrawGram - Render Feynman diagrams from FeynDrawGram JSON files

This package renders diagrams produced by the FeynDrawGram web app. The input is the JSON exported by the "Save" button in the app.

Typical use:

#import "@preview/feyndrawgram:1.0.0": feyndrawgram

#feyndrawgram(json("my-diagram.json"))

Parameters:

• use-cetz-decorations (default: false) If false, photons/gluons are drawn by sampling exactly the same analytic path the web app shows on screen. If true, simple straight wavy/gluon edges with multiplicity 1 use CeTZ' native decorations.wave / coil; curved or multi-line oscillating edges always fall back to sampling so that parallel waves stay in phase.
• unit (default: 1pt) Length of one canvas pixel in document units.
