This is a FAQ; did you try searching for previous PF threads? This very question was discussed as recently as a few days ago.

If you take and combine two of the spatial dimensions say z and y then have time be your third dimension on a graph it is pretty easy. Its used in a lot of examples and what not in books.

We can't visualise it we don't visualise in 4D. But here are models to help us understand.
