Checking disc space usage

[TheBandit]

How do you check disc space usage on Mac OSX Mountain Lion?
And I don't mean checking for how much space is available, i mean checking to see what is taking up every GB of space.

That still doesn't show what is taking up hard drive space, there is a large number under "other" but I don't know what "other" is.

Another option which is more comprehensive is to use this terminal command
sudo du -d 1 -x -c -g /

I prefer to redirect it to a text file (this puts it in your Documents folder
sudo du -d 1 -x -c -g / > ~/Documents/du.txt
