I've seen a number of repeated questions around the general Plexus Network topic, mostly of the "what is this called and how to make it?" variety, some specific to motion graphics like After Effects, some aimed more at Illustrator / Affinity Designer style vector illustrations - we've a fair few very good answers out there (especially some created today) with a number of excellent resource links etc - seems to me that it's coming up often enough to consider a canonical on this one.
