I don't think EA works on units? Especially not on WPs?
You can get a tech tree by starting a full tech game and exporting the tech list in the research window. It does not export everything that tech gives you, but it shows all tech reqs IIRC. And with technologies often named after what they are (I am very creative

), it works fairly well. I will probably make a real one at some point, but this will be good for now.
