September 27, 2024is possible to use mermaid beta diagrams (architecture-beta)?

It probably doesn't require a Docusaurus breaking change (ie ... More on github.com

Custom icons for Mermaid diagrams in Docusaurus | Simon Painter
September 24, 2025 - This has been addressed by using the Iconify library which has a large collection of open source icons.

Mermaid config can be configured through the plugin config: docusaurus.config.js · { mermaid: { theme: 'dark' } } caution · When passing config to the <Mermaid> component only the first instance should have the config passed to it.
