In teaching Big Data, we often travel. Lately, in our view, Big Data is picking up the world over, not only in the US. Israeli Spark meetup are just as advanced as the ones in California. So we asked our artist to show all the places where we have been. That was too hard though, so we just used travel pointers. But the elephant is real.
(In fact, this post is written on a Turkish Airlines plane - thanks to very good WiFi).
