How to store a large chart on disk

I have a large graph of several 100 GB, so I can not store it in RAM. A graph has polyhedra, and there are labels for each edge. I would like to fulfill queries like:

  • Show me all the edges obtained from the specified node.
  • Show me all the edges between two given nodes.
  • Select 1000 random pairs of nodes that are connected, and show me all the edges between them.
  • Select 1000 nodes selected at random.

What is a good way to store graphs on disk for these kinds of queries?

This is for one high-performance PC, not for distributed configuration. My preferred programming language is Python.
