Hi, and welcome!
Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers. Also, when applicable, check homework policy.
Networks are hard to visualize, and at some point it's necessary to fall back on plots of sub-graphs and to show the detail separately for each subgraph until the visual complexity is under control.
Take a look at the ggnetwork package, for one approach.
