Interesting and much needed!<p>Few questions if the maintainers / owners read this:<p>1. what is the license? it seems to be not commercial friendly at the moment, but I couldn't tell if it's GPL / AGPL or something else<p>2. what are your plans for supporting network/graph data structures, graph analytics etc.<p>3. visualisation plans?<p>4. is the target to become a fully fledged BI tool? compete with the likes of Tableau / Spotfire only on top of Big Data? (if so I'm very interested!)
