RE: Friday Blue - Color challenge - Rarity.

Good question). Search for plots is an integral part of creativity, to find what you are looking for where, perhaps, it has not been seen, sometimes, for this, you need to strain your brain and prove to yourself that it is.
For example, I do not see evidence of the brain in statistical posts, this is just a fait accompli that does not need to be proven, but I respect people who spend their time compiling statistical reports.
