I am not sure about how to present this question because I don't know the animation term that I should use.

I need to know about this tree presentation animation. As it is appearing form root to top.

Please take a look on attached .gif file and let me know if anyone know about this animation or if you can guide me with example.

I will really appreciate.

Thanks for your time.
