What software can be used to make Critical path/flow diagrams?

You can embed mermaid uml markup in github and gitlab issues

On a similar note, you can embed Draw.io markup when exporting Draw.io diagrams, meaning the image contains the metadata required to open, modify, and generate a new image (which itself can also contain the new metadata).

Mermaid has its place, but Draw.io is so much more flexible.
