Gun‑Avatar is a tiny library that deterministically turns a GUN SEA public key (an 88‑character string) into a unique avatar image. It supplies a plain‑JS function, a custom HTML element, or an automatic‑class handler that output a base‑64 PNG or SVG (with optional embedded data, dark mode, round mask, symmetry, etc.), aimed at developers building decentralized applications with the GUN graph database who need visual identifiers for user keys.
