Like I said, they are ballpark figures but overall, useful.
Green is free, yellow is semi-free, purple is unfree.
So, you can look at the map, Outer Mongolia over China is green, it is actually somehow, a free nation, India is a free nation. There's Ukraine, "semi-free". Not sure for what year this is, I think a recent year, Venezuela was rated semi-free only a few years ago, now, it's purple like Cuba:

So, just for a quick glance, I think it tells one a lot.
