• Hello. You won't get any help doing this huge tree without sharing a minimal working example of what you already tried, and asking for specific solution to a specific issue you're struggling with. Aug 5 at 13:01
• Do you mean levels of a tree? You can count how many levels there are: I would say it is about 9 ... But this and also whether this actually has any meaning depends on how you are going to type this tree. Aug 5 at 22:03
• Welcome to TeX.SX! Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. Aug 6 at 13:30
• Hello, Thank you very much. I m working on it and will post the code. The main issues is how to remove fork down to produce linear diagram. Aug 6 at 17:50
