Mermaid flowchart: usage and export guide

What is a Mermaid flowchart?

A Mermaid flowchart is a text-based diagram that belongs in Mermaid documentation. It uses flowchart TD style syntax so the source can live beside markdown, code examples, requirements, and architecture notes.

This diagram type is best for showing steps, branches, and outcomes in a business or technical process. Because the source is text, it works well with AI assistants, version control, documentation reviews, and repeatable export workflows.

Common Mermaid flowchart use cases

Mermaid flowchart pages are useful when teams need a visual that stays editable. Common uses include process maps, decision trees, approval workflows.

In Markdownyi, you can write or paste the diagram source, preview the rendered output, and include the visual in a Word or PDF deliverable when the diagram belongs with a larger document.

• process maps: document the concept with concise labels and supporting prose
• decision trees: document the concept with concise labels and supporting prose
• approval workflows: document the concept with concise labels and supporting prose

How to create a Mermaid flowchart

Start by opening the Mermaid editor or adding a fenced mermaid block in markdown. Use flowchart TD as the starting syntax and keep the diagram focused on one purpose.

Preview early, then refine names, grouping, direction, and labels. A diagram that looks good in a browser preview is much more likely to export cleanly into a Word document or PDF.

Export and documentation tips

Use short node labels and split very large processes into smaller diagrams. For formal documents, place a short paragraph before the diagram to explain what the reader should notice, then add a short paragraph after it to capture decisions, assumptions, or next steps.

Use Word export when reviewers need comments or edits. Use SVG, PNG, or PDF exports when the diagram is a standalone asset for slides, tickets, wikis, or architecture records.
