RGraph is Open Source Software
RGraph was originally started as a commercial project - licensed using the Creative Commons BY_NC license and it was like this for a while but was then switched to an Open Source license and that's what it is now, so it's Open Source Software (FOSS).
As a result, it's totally up to you whether you use it or not! You can read more about me on the About page...
The MIT license is well known as an Open Source license and means that you can use RGraph for any purpose you wish - non-commercial or commercial.
You can include it in your own software, modify it and distribute it without asking for permission or paying any fees.
There is nothing that the end-user needs to do or buy and there's no requirement for you to share your changes should you make any. Basically: You can do what you like with it!
Here's a list of people who have contributed to the RGraph project in the last 12 months. Thanks very much!
