Matt Turck and Shivon Zilis of Bloomberg Ventures recently made this graphic that maps out the ‘big data ecosystem’.  It’s far more comprehensive than the one Forbes put together a few days ago. I don’t just say that because he includes yours truly (while the later did not), but simply because it illustrates just how many players are in the space.  

And perhaps I’m projecting but at also does a good job of capturing just how crowded the market is.
