c3 is decent, but it is no longer maintained and with 675 issues and counting, it's the wrong choice for any new project. We've had it in production for a coup

c3 is decent, but it is no longer maintained and with 675 issues and counting, it's the wrong choice for any new project. We've had it in production for a couple of years now. The best thing about it was it got us off the ground quickly but at this point I think we've likely sunk more hours into debugging issues and hacking features than it would have cost us to have built it with d3.
