I just looked it up and it's actually called the Rumor Map apparently. It's pretty important to organize all the things you find in a loop and check yourself to see if there is more to uncover on some plot point.

If you get in your ship it's opposite the pilot seat. I'm sure it was pretty maddening to not have that tool and hear people say such high praise about the game lol.

If you haven't been spoiled on it, you might find the game a lot more enjoyable giving it another shot some day!
