A matter of perspective

The Senter cluster diagram shows two different 3D perspectives on the 2009 same data. It can be confusing if one does not fully realize this. For example the chart on the right seems to show that the violet dots and the pink dots are close together. But of course they are not, as we can clearly see from the chart on the left. It is just an illusion of perspective. This is probably obvious to most every one but it may have confused a few people.
