Visual indication of last nodes of a tree

[kisst]

When a map is rendered , a visual language does not make it trivial that an item has no sub-items, so user might try to open / close them, @anttisalo any suggestions for a clear indication, which does not take a massive toll on the implementation, color or shape changes, something less taxing then a full new GUI ?

Let me have look at the source and see how the expanded/collapsed states are now handled.
The current solution is IMO on the right track but needs to be more verbose not allowing the dot state to change if there are no children under it.

Maybe a + and - would work, and empty if there no child, but also the no click action is a good point I was thinking only in UI, but it is function change as well.
Saying this ... I'm unsure how would we draw into the circle 🤔

[anttisalo]

The map is made using SVG. The states are inline styles and shouldn't be a problem to change to use classnames. I'll take a look when I find a free slot today

Why not just make the border of the circle node grey?

[kisst]

That works as well, fine by me, the extra is as Antti pointed out the action should be removed / modified as well, as if the user still wonder on around and click on it that would get the gray back to blue.
And I got our UX expert into the conversation as I really don't want to add User Manual, it really should be self explanatory how to use.
