I didn't check mermaid for bng, but had checked it before (I like visual representations of knowledge, no matter what they are for). Although I found it interesting, my gut feeling here was that if my problem's solution (at that point it was just out of curiosity) was going to be JS-based at some point, I should go directly for D3 (I already had experience, but not recent, with D3). Mermaid uses D3 under the scenes, so depending on your specifics it could be the best solution anyway, though. Performance wise, I'd expect it to be OK (D3 is pretty fast in most cases) although if there are any issues down the road, fixing them from such a high level library as mermaid could be daunting (it's "easier" to move down from D3 to paper.js or g.js or any other high performance canvas renderer if the case arises).
