Stupid graph, that's comparing apples and oranges. Yes products are identical, but the distribution is totally different.
Facebook intentionally was only on college campuses. It let them scale slowly and work their way up the chain so to speak.
Twitter was crushed by growth and didn't have an existing user base to tap into.
Google+ growth is impressive, but it's built on top of how many Google Accounts, GMail accounts, Chat accounts and so on? It was designed from day 1 to get to the same 700+ million users that Facebook had.
I doubt either twitter or facebook ever considered the idea of getting a billion people to use them when they launched.
Also, even more than Buzz or Wave, Google+'s only value lies in inviting your friends. So, people invite their friends. It's like a social game, it only is fun if other people play it. It is in everybody's best interest to invite their friends, otherwise you are just sharing with Google's servers. If I wanted to work on a wave, it was with 1-5 people, if I want my social network on Google+, I'm going to invite 100+ people.
It in no way illustrates that, for the reasons programminggeek provided.
Google+ is making a huge splash, that is about the only meaningful statement that this graph illustrates. It doesn't suggest that they could dethrone facebook because there's a hell of a lot more to making a good social network than how quickly it gets ten million users.
For me and my friends, google+ is a dead zone. I signed up to check it out, and barely have looked at it since. I would like to use it some day, when more of the people I really want to connect with are on it, but there's really no certainty that it will make it to that point.

Apples. Oranges.
