By the way, heard that they change the Palin requirement of 5'000 LY to new 3'000 LY, but need to confirm this tonight.
Nicely done. At the same time you might want to take a look here: http://inara.cz/galaxy-engineers

It covers most of what you brought into the graph, except that you have to click the engineers to see the requierments to reveal and unlock them. Your solution actually is more clean and easy to use, the inara version is more powerful in the long run.
