Are there any open-source instruments with easy-to-write (maybe YAML-like) syntax which allow to describe tech tree in text file and (preferably) render it by some diagram engine like graphml(yEd) or graphviz?
I tried to use WYSIWYG diagram editors (yEd) for this. But I find very frustrating to edit tech trees in such programs since you need to repeatly type in labels like "cost:/effect:" or scroll over multiple lines to change tech cost, for example. I want to see and edit tech tree data in a plaintext form which is most convenient for me (kind-of software engineer and computer geek, eh)
Not sure this is suitable SE community for such question but don't know where to ask it anyway.
