Hi @arokem, why do you use here the jet colormap? Is that so that you get the same colours in every run? Or for the looks? You could have used random colours instead which would need less dependencies. But maybe it was more ugly? Also if you generate many clusters (more than 100) many clusters will look very similar (colorwise) with the jet colormap.  With QB the big clusters will be first, so many big clusters will have the same colour. Am I missing something? What do you think?
