I did install the Graphviz from this link: **<http://www.graphviz.org/download/>**, and since I have windows, I used this version: **graphviz-4.0.0 (64-bit) EXE installer [sha256]**.
I am not familiar with this program, and now I don't know where I should write my codes? There is no shortcut on my desktop. Do I need any other software like Python to be able to use this program? I couldn't find any tutorial for a super beginner; I would be grateful if someone could help me!
