That infographic would have been much better as a regular table, instead of this circular thing. It seems to me as if it is not intended to be actually used, only to look nice.
It's a dreadful graphic. No information leaps out at the viewer, you have to hunt through two tables for the meanings of the letters and numbers. It takes an effort to find the letter for any given block, or to find the block for any given letter, in radii far from where the letters appear. It's difficult to tell apart yellow and gold, or grey and silver: the key only serves to highlight how indistinguishable the colours are.
And since this graphic does not work, I cannot see it as beautiful. It is an ugly sacrifice of function to superficial prettiness.
