Suppose I have a group of 3D vectors that all originate at zero,zero,zero. I want to see which ones cluster together in 3D space and if there is more than one cluster. I guess this simplifies to just charting 3D points.

So if for example I had a range such as:
10,32,20
11,16,17
55,21,10
99,44,33
88,17,22

How would I plot this as a 3D chart of points.
