The **diamond‑square** package implements the classic diamond‑square algorithm for generating Minecraft terrain heightmaps. It provides a Node.js generator that can be plugged into a `prismarine-world` instance, letting developers create procedurally‑generated worlds for any supported Minecraft version (e.g., 1.12‑1.17+). It’s aimed at Minecraft server or bot developers who need a simple, version‑agnostic way to add realistic terrain generation to their projects.
