No, taking that as evidence for racial clustering is a mistake; see for instance this discussion by Bolnick. In short, while the techniques may have been automatic, they were based around taking some number of clusters as an assumption and so couldn’t help but find them somewhere.
If you keep that in mind, you can see how the same chart fits as well or better with everyone on a single continuum or genetic cline, and from what I can tell that’s the current consensus. You can certainly cut that distribution into any number of pieces, but like MarjaE suggested, the divisions will be essentially arbitrary.
Also, this is all very off-topic for this thread.
