    Dataset information                                                            
    Network was collected by crawling Amazon website. It is based on Customers Who 
    Bought This Item Also Bought feature of the Amazon website. If a product i is  
    frequently co-purchased with product j, the graph contains a directed edge from
    i to j.                                                                        
    The data was collected in June 01 2003.
