topologically ok.

they are just simple boxes drawn around all nodes.

Thanks Hamish,
I never noticed those boxes, but it depends on the zoom level, as their size is fixed.

It wasn’t a foundamental question, but I wanted be sure eveything was ok with my layer.
Besides in the courses I teach students are able to ask similar questions and I want to be ready! :slight_smile:
