Interesting approach. I make heavy use of Mermaid as I find it easier to make small changes and bulk generate-and-copy for publishing elsewhere. But being able to update the diagram and automatically generate the output files is a nice hybrid.

I use Mermaid too, but a lot of that comes down to the fact that it's easier to generate it with Claude.

It can be exceedingly useful to do this if you have a big log file and you need to have a diagram of a trace, even if you're not sharing it on a blog.
