The Mermaid Tools plugin for Obsidian.md brings a convenient toolbar to your editing experience, making it easier to create diagrams and visualizations using Mermaid.js. With this plugin, you can quickly access common Mermaid.js elements, such as shapes, arrows, and more, without having to remember their syntax. Simply click on an element in the toolbar, and it will be inserted into your editor for further customization. The plugin also includes a settings panel where you can create, edit, delete, and reorder your custom elements, giving you greater control over your diagram-making process. Whether you're creating flowcharts, sequence diagrams, or other types of visualizations, Mermaid Tools simplifies the process and streamlines your workflow.

The Mermaid Popup plugin is a convenient addition to Obsidian, allowing you to display diagrams from various formats such as Mermaid, PlantUML, and Graphviz in a zoomable and draggable popup. With this plugin, you can easily view and interact with your diagrams without taking up too much space on the page. The popup is accessible through a customizable hotkey or by clicking an open button at the top of the screen. You can then use your mouse, touch gestures, or UI buttons to zoom in/out, drag the diagram around, and even close it when you're done.

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 Mermaid Themes plugin allows Obsidian users to customize and apply themes to their mermaid.js diagrams. Users can either provide a complete mermaid theme object or modify specific parts of the base theme, with the plugin merging changes seamlessly. This enhances the visual appeal of diagrams by supporting advanced theming options. Users are required to use an alternative code block label (`merm`) instead of the default `mermaid` to integrate themes. The plugin leverages mermaid.js theming features, providing a flexible way to improve diagram aesthetics in notes.

The Mehrmaid plugin extends the capabilities of Mermaid-JS codeblocks in Obsidian, allowing users to render Obsidian-generated markdown inside Mermaid node labels. This feature supports a variety of markdown elements, including links, tags, codeblocks, and Mathjax expressions. Users can create complex diagrams with customizable node contents, including embedded images, formatted text, and mathematical formulas. Mehrmaid simplifies the process of visualizing data and relationships within Obsidian notes, making it a useful tool for creating dynamic, interactive charts directly from markdown syntax.
