History of RGraph
RGraph started out in 2008 as a commercial endeavour - licensed using the Creative Commons BY_NC license. It was like this for a while but was then switched to an Open Source license and that's what it is now. As a result you don't have to pay me for using it, buy me a gift or take me out for a drink. Use it; don't use it; it's up to you!
