Editable Gantt chart example

Release plan Mermaid diagram example

Updated 12 September 2026 · Renders with Mermaid 11.17.2

Edit this dependent release schedule in Mermaid, inspect the rendered result, and adapt the working source for your own documentation.

About this example

This dependent release schedule example is designed as an editable starting point rather than a finished specification. In the rendered diagram, design, build, and review tasks use explicit dates and dependencies. Read the structure once before changing the source so identifiers, labels, and connections stay aligned. The example is intentionally small enough to test after every edit, but it includes the syntax needed to communicate the central relationship. Open it in mermaid.tools, make one change at a time, and keep the Mermaid source alongside exported images so the diagram remains maintainable.

Adapt it

• Change the kickoff date, durations, and section names before adding parallel work.
• Keep identifiers short and stable while changing the visible labels for your audience.
• Preview after each structural edit, then remove sample nodes that do not represent real information.
• Export SVG for scalable documentation or PNG when the destination expects a fixed image.
