Nice and simple. I like it! How about the ability to add animation, and export as an animated gif or video? Why not provide a couple real-world (more detailed) examples of what it can do? Sure its simple, but if you want people to "get it", one of the best ways to do that is to show it in action. Also, have you thought about the ability to add forks?

More examples makes sense! I'll add that after adding some more visual styles / more customization options. I haven't thought about forks yet, but sounds like it would be useful. I remember using coggle.it which is quite convenient and supports forks
