Tree Drawing Using Reingold-Tilford Algorithm

Hi, there

About a month ago, I worked on a simple tree-drawing software. Existing explanations of the Reingold-Tilford algorithm confused me a lot. I decided to try to explain it by myself.

In my blog post, I really tried to cover every aspect and every step of the algorithm. Hope someone will find it useful.

If you have any ideas for improving my explanations, please share.
