Hi guys. I am reading several papers about financial market and authors show the possibility to represent this market as a graph in which nodes correspond to traders and edges represent trading relationships. Which programming software could be a powerful tool to write a such code? I am curious about that (unfortunately I have not experience and I am not familiar with codes. I hope you can suggest me a software, an algorithm and/or whatever is helpful to understand and trying to replicate some of their works ( I would like to say "just for fun" though I don't guess I could call this a "fun" work...). Many thanks.
