Vithanco Graph Language (VGL) Guide

Learn the VGL syntax for creating and editing graphs in text format

VGL Guide — User-Defined Notations (`vnotation`)

vnotation lets expert users define their own notation schema inline in a VGL file, without requiring any Swift code changes. Everything that built-in notations provide — node types, edge types, lay...

VGL Guide — Metagraph (visualizing a notation)

A metagraph declaration renders the structure of a notation itself as a diagram. Because a notation is a graph (its NodeTypes are vertices and its EdgeTypes are edges), it can be visualized directl...

VGL Guide — Concepts

The Vithanco Graph Language (VGL) is a human-readable text format for creating and editing graphs. VGL provides a simple, declarative syntax for defining nodes, edges, groups, and their attributes.
