Kroki

The Kroki plugin allows you to render diagrams in Obsidian, using the Kroki server or a custom one. With this plugin, you can easily include various diagram types such as sequence diagrams, flowcharts, and more into your notes. To use it, simply create a fenced code block with the diagram type specified as the language, and add your diagram code inside. The plugin supports multiple diagram types and allows for customization through options.
