Is it possible to visualize a group of vertices with one color?

e.g. For one label, I'd like to group them several categories, and visualize them using different color per category. Is it possible to do that/

Currently color grouping works per unique vertex label, but not per vertex property. You could contribute this feature to allow color grouping per vertex property instead and I will be happy to review it.
