mmd
What is a .mmd file?
text/vnd.mermaid
An MMD file holds a Mermaid diagram written as text (diagrams-as-code): a concise syntax that describes flowcharts, sequence, class, and other diagrams which a renderer turns into an image. It is widely embedded in Markdown and documentation.
How to use a .mmd file
Use an example Mermaid file to test diagram rendering, Markdown pipelines that embed Mermaid, and diagram-to-image conversion.
Download example .mmd files
- Mermaid Flowchart (MMD)A Mermaid flowchart of an order-fulfilment process as diagrams-as-code — for testing Mermaid rendering, diagram-to-image conversion, and Markdown pipelines that embed Mermaid.
- Dependency Graph (Mermaid Flowchart)The dependency graph as Mermaid, for embedding in Markdown documentation — labelled edges carry the declared range and a classDef highlights the two diamond joins. Every package, version, hash and licence is fictional — the tree describes nothing real.
- Mermaid Pipeline FlowchartThe shared six-task ETL topology as a Mermaid flowchart, with mixed node shapes, a subgraph, a classDef and %% comments. The Mermaid twin of the Graphviz fixture, for scoring diagram-format converters against one known answer.
- Mermaid Deployment State DiagramA Mermaid stateDiagram-v2 describing environment promotion with canary and rollback transitions, start and end pseudostates, and a note block. A second Mermaid diagram type, so a renderer is not only tested on flowcharts.
