UFO:Afterlight Technology Graphs

Description

Buildings (png), Equipment (png), Research (png), Trainings (png)

Research and Buildings (png)
Both these entity types on one graph.
I think this is the best graph in terms of being usable.

Complete Tree (svg)
A combined graph of all four entity types.
Svg is a graphics format which should be viewable in Internet Explorer and FireFox.
