I installed the python3-pyyaml and python3-matplotlib, but I couldn't figure out what package "seaborn" is part of?  "yum search seaborn" doesn't find anything on my el8 system, nor does "rpmfind" return any packages for this.

While not as pretty, I expect just picking colors by a 3-byte hash of the component ID and stripe index would get you something usable if "seaborn" was not installed, or a hash of the object ID, or similar?
