I think the concept is cool, but I tried clicking on stuff I'm familiar with, and I don't get the circles thing.
For example, the French communist party (PCF) has Jacques Chirac in its first circle. He has briefly been in this party, but he mostly remembered as right-wing.
Also the Fiorentina football club, should have its hall of fame striker Gabriel Batistuta in its first circle -he has a statue- while he appears in the outer circle.
