What is the average degree of the 100B nodes in this graph? If it's anything north of like...2 (or maybe 1.0000001, or less, unsure), then this sounds about as intractable as "visualizing Facebook friends" (times 30)

Comparing it to a rendering engine I think is a bit of a cheat unless the points do have some intrinsic 2-D spatial coordinates (and no edges beyond immediate adjacency). You're ultimately viewing a 2-D surface, your brain can kinda infer some 3-D ideas about it, but if the whole volume is filled with something more complex than fog, it gets tricky. 4-D, forget about it. 100-D as many datasets are? lol.

Having worked in a lab where we often wanted to visualize large graphs without them just devolving into a hairball, you'd need to apply some clustering, but the choice of clustering algorithm is extremely impactful to how the whole graph ends up looking, and in some cases it feels like straight deception.
