I'm trying to do a tech tree GUI for my game, but i have limited width and the tree has alot of branches, the problem is if I make them small to fit the width, the tech tree is too small to read.
For example the AOE one is very large (in width):
I could allow scroll bar but as its web based, scrolls are quite ugly. So i was wondering how to deal with branches which slowly cause the tech tree to get wider as you go down the tech tree and how you would fit such a design in a limited space.
Are there different known designs for tech trees that any one knows of so i can look at their types. I don't know the names given to the types of tech tree layouts. But am hoping to find one that is not overly complex for the user aswell.
