Editing a complex diagram and integrating that into your documentation shouldn't be hard. The Mermaid.js library makes diagrams of all types accessible through simple markup. Using the MediaWiki extension, brings the power of Mermaid diagrams to your wiki. The Semantic MediaWiki (sandbox) website shows some examples of Mermaid markup plus the MediaWiki parser function https://sandbox.semantic-mediawiki.net/wiki/Mermaid
