Only because I turned off icons and arrows, those are unbearable mess 
. Unlike @Hexara’s centre node surrounded by objects with the same icons; that’s very neat.
To establish more constellations, more usage of relations is the way to go. The more connection objects have, the more constellations it accumulates.
Unlike many who organise or control their graph, I bombard my objects with relations that conceptually connects. I respect the natural/existing force behind the contents and let connections manifest themselves; I am here to observe and witness, and then work with the contents.
This approach relies heavily on the ability to reduce noises, like local graph and graph filter feature. So it is actually really hard to understand my own (global) graph .
Also, even though it is ‘beautiful’, I am not sure this is how my graph should behave
