Support mermaid format in terraform graph

[fishpen0]

Use-cases

Github now natively supports mermaid diagrams in its markdown syntax. It would be useful for terraform graph to be able to natively export these for use in repository documentation.

Proposal

Add native support for the mermaid diagramming format in the terraform graph command

Workarounds

It looks like there is one very old project that tries to make this work externally: https://github.com/hmalphettes/terramer

Hi @fishpen0, thanks for the enhancement request!

Graphviz is not good for large deployments :(

would be great to see mermaid support here 👍

In my research I came across two existing options:

• Convert output of terraform graph to Mermaid using sed: https://www.heaton.dev/2022/05/use-terraform-graph-in-mermaidjs/
• Directly generate Mermaid code: https://github.com/RoseSecurity/Terramaid
