Visualization of Self-Organizing Maps (U-matrix with points)

Hi!

I am in doubt of what I'm actually visualizing with my U-matrix of the SOM.

I have a lot of data of which I've removed a label from.
This data is fed to the SOM which are then trained. The output of the SOM are then joined with the removed label from the original data.

This joined dataset is visualized with a U-Matrix - on top of that, the points corresponding to the label is plotted on top of this U-Matrix.
What am I looking at here? I'm in doubt of why and how the points distribute as they do.

I hope it makes sense 

Cheers!
