The Export Graph View plugin allows users to export metadata from their Obsidian vault as graph files in `.mmd` (Mermaid) or `.dot` (GraphViz) formats. It provides a flexible way to visualize connections between notes and attachments without being restricted to a specific external tool or pipeline. The plugin includes a memory safeguard feature, allowing users to set a maximum node limit to prevent performance issues, particularly for large or complex vaults. Users can access the export feature from the settings menu or the left-hand side panel, making it easy to generate graph-based representations of their vault structure for further analysis or visualization.

The Obsidian Graphviz plugin allows users to create and render Graphviz diagrams directly in Obsidian using the Graphviz DOT language. By integrating a local Graphviz executable or using experimental d3-graphviz support, this plugin enables seamless diagram creation within Obsidian. Users can define their graphs using DOT syntax within fenced code blocks, with immediate preview rendering of the diagrams. This plugin is perfect for users who want to visualize complex relationships, workflows, or processes in their notes, making it a valuable tool for visual thinkers and technical documentation.
