Mads Tinggaard Pedersen:
 Hi all,
 I am a student writing my master's thesis. I am, among other things, 
 analyzing the degree of anonymity in a network and would like to investigate 
 real life examples of TOR networks.
 However, all I could find is https://metrics.torproject.org/network.html 
 which can tell me about the number of relays in the network.
 
 I am writing to you to ask, if there exist some data on the shape of the 
 network, perhaps based by country?
 
 I am not concerned about the practical stuff, such as IP addresses, version

 It does not matter if it is old data.
 I hope you can help me out.
 
 Sincerely

 what nodes in the network graph is connected to one another.

There is no real shape or topology or any fixed node-to-node connections
to speak of, really. Each client picks 3 nodes randomly (with the 1st one being
from a set of chosen once and kept long-term Guards), then builds a so
called circuit to route a new connection via them. So a structure of the
bulk of the network is a formless cloud (the word everyone loves so much),
with maybe some silver lining representing Exit nodes.

You might like https://compass.torproject.org/

You might also like https://metrics.torproject.org/data.html

 I am not concerned about the practical stuff, such as IP addresses, version 
 numbers, etc. Only what nodes in the network graph is connected to one

That leaves you with the trivial graph: the Tor overlay network is
a clique.

What are you actually trying to learn?
