OGDF C++ library provides some graph generators, I made it possible to use them from terminal, not by writing C++ client code. Got some pleasant pictures, here they are.
- Graphs of ~32 nodes, FMMM layout.
- Graphs of ~512 nodes, FMMM layout.
- Graphs of ~512 nodes, ForceAtlas2 layout.
Each node is labeled by it's degree - count of incoming/outgoing edges. Colored accordingly, from blue to red.
Powershell code for creating these pictures goes like that:

I suspect there were no issue in the first place. A lot of time ago, if torrent client encountered files are missing, you had to run long process of verification for them to become available for seeding.
Now, if torrents switched to "files are missing" you can restart torrent client and seed like if nothing happened. No need for categories even. Also, function "Set location" can be used to move torrent to external storage.
