Repeating what others said here: I doubt anyone actually needs to see 1B (or 100B) nodes to make whatever decision they need to make. They probably need to see the X nodes that matter?
If you're fully "zoomed out", is seeing 1B individual nodes the most useful representation? Wouldn't some form of clustering be more useful? Same at intermediate levels.
D3 has all sorts of graphing tooling and is very powerful. It likely wouldn't handle 1B nodes (even if it did, your browser can't) but it has primitives to build graphs
