    This dataset was made public by the Federal Energy Regulatory            
    Commission during its investigations: it is a partially                  
    anonymised corpus of e-mail messages exchanged by some Enron             
    employees (mostly part of the senior management). We turned              
    this dataset into a directed graph, whose nodes represent                
    people and with an arc from x to y whenever y was the                    
    recipient of (at least) a message sent by x.
