Amazing, I made an account on the forum just to say this and to thank you. The 2d graph is interesting, but this evokes something else. I described it to my daughter that this was a “universe” rather than a mind map, and it feels like I can navigate my stars, and the stars have their own planets. I searched for this but can you change the color scheme? I did see the “Link particle color” which seemed to not have any affect. This should be Graph 2.0 in the Core Plugins!
