To pull off a $20 billion ponzi scheme, you need a broad web of social and business connections. In the case of Bernard Madoff, the network of feeder funds and sub-feeder funds that funneled investors’ money his way was particularly complex. For a striking visual depiction of this complex network of funds, check out this interactive network map: Bernard L. Madoff Money Flows & Feeder Funds.
The map was created by Orgnet.com, a company that provides social network analysis software and services. Orgnet founder Valdis Krebs provides more information about his Madoff map at his blog, The Network Thinker.
