I'm intrigued by your question as I haven't found a good one that was open

I have used the sort of "freeware" yEd https://www.yworks.com/products/yed .
It's quite sophisticated and has worked for nearly everything I needed to do.

Hi;
What is a good alternative to 'dia'?
Open source, works on MacOS arm64, or comes native with MacOS.
Just want something very simple (elementary flowcharting).
Thanks,
