Mermaid Blocks

Mermaid Blocks lets you insert interactive diagrams into your content using the block editor. Simply add a new block, enter your Mermaid syntax, and the diagram renders instantly. You can create flowcharts, sequence diagrams, class diagrams, and more. Each diagram is fully editable—just click to update the code. The output is responsive and scales to fit your layout. Ideal for technical documentation, tutorials, or any content that benefits from visual explanations. No third-party services needed; rendering happens locally in the browser. Supports real-time preview as you type, enabling rapid iteration. Export diagrams as SVG for use outside the editor. Integrates seamlessly with existing themes and plugins without breaking styles.
