As for 4D and 5D - try to use right button and drag the image. You will see that different parts change their color and some points go deeper in the screen while other go backward. Actually it’s rotation in the (depth, color) space. For example, if you right-drag on right, points behind the Pacman go violet, points before it go yellow, yellow points go from you in the screen and violet points go back to you. Up-drag does the same with red/blue pair.
It may be useful when you try to turn in the pass that goes to the side of your way, looks very short and has far end of some bright color. All this means that this pass goes from your main 3D space in some another direction, and it will be difficult to turn in it in 3D. So it’s better to make "color" rotation that will move far end of the pass deeper, and then orient it along Z axis. At first it is very tricky, but I hope that with some training we’ll be able to understand all this 4D/5D turns and use them better.
Also there is right-click that changes screen coordinates to color coordinates and back. But when I use it I quickly get very flat glaphs and it’s difficult to make them 3D again.
