I can very flexibly customize my graph, and this is a great advantage. Other services also give me the ability to make mind-maps, but nowhere can I configure them as flexibly as here. And the interface is quite simple and easy to use. Review collected by and hosted on G2.com.

I really don't see any. I've tried many alternative services and they don't even come close to the capabilities of Linkfacts. Review collected by and hosted on G2.com.
