Why not use Blazor Diagram to draw nodes?

I guess it depends on your application, and what it is designed to do. Mermaid is a popular diagramming markup used on markdown documents. So, if you want to render markdown documents that contain Mermaid syntax, then I guess Blazorade Mermaid would be a better option.

If you only want diagrams, then Blazor-Diagrams might be a better option. I would consider that too. If I was building some kind of dashboard type of app with a lot of charts, then I would consider Blazor-Diagram too.

How are U going to implement interactions, pan, zoom, provided default by blazor diagram

[MikaBerglund]

I won't. Mermaid, the original Mermaid JS library supports very limited interactions. If you need interactions like pan an zoom, then Mermaid and Blazorade Mermaid is not the right choice.

As I said, if you want to render markdown documents with Mermaid diagrams in your Blazor app, then Blazorade Mermaid is a good choice. Is it the only choice? Of course not. Blazor Diagram and Blazorade Mermaid are in many aspects very different libraries with different use cases. However, there is one aspect where they both are very similar - They aim to "free" the developer from having to deal with JavaScript.
