Hello everyone,

I want to make that can generates you a tree diagram with the parameters you give to it. So, I first tried to think about what classes I was going to use...
I think I'll use a 'node' class, a 'nodeCollumn', but I don't know where to start...
Could you help me? Or share me a example, or a program that has already been done?

Thanks, and sorry for my bad english, I come from far away ^^
