Hi,
The number of device-to-device links is fundamental to mesh networking.
Mesh network devices know network conditions better than a sysop, so are designed to operate autonomously. A diagram can only really show where a device has poor coverage to peers, and where an other mains-powered router could help reinforce the mesh. In fact, the mesh map may not be telling you what you believe it does.
Other networks can be visualised by techniques like a heat map, but as mesh works link-by-link, that isn’t a useful view.
Signal strength / quality could be shown by thicker lines or colour coding as an option. That might help spot interference and poor mesh.
I’ve seen other platforms offer dynamic positioning of nodes as you zoom in, but that doesn’t change the need to show individual links.
This is not rocket science, this is rocket engineering! 
(the science is very simple - the engineering is anything but)
