Custom icons for Mermaid diagrams in Docusaurus
I have tried to move to exclusively using Mermaid for diagrams in my blog posts and documentation. It is a great tool for creating diagrams in a text based format that can be version controlled and easily edited. One of the limitations I have found is the lack of custom icons. This has been addressed by using the Iconify library which has a large collection of open source icons. Combined with the architecture-beta diagram type in Mermaid it is possible to create some great looking diagrams that go beyond the basic flow diagrams I have been using until now.
