The Kale Graph plugin enables users to create and visualize graph theory structures directly within Obsidian. It uses a simple custom syntax to define vertices, edges, paths, and adjacency matrices. Users can customize graphs with features like directed edges, automatic vertex creation, and invisible vertices that maintain subgraph structure without being displayed. The plugin allows for visual clarity and flexibility in graph creation, making it useful for modeling relationships, visualizing complex systems, and representing concepts in a structured format. With support for flags to adjust graph behavior and a variety of edge definition methods, Kale Graph offers users an intuitive way to explore graph theory principles inside Obsidian. Customization options for graph appearance are available through plugin settings.
