File talk:Six degrees of separation.svg

I don't understand this diagram. The circles appear to be miscolored if they represent degrees of separation. For example, the circles that branch off the first orange circle should be purple, and so on. Second, the diagram is not a particularly good illustration of the concept, since there is no correspondence between spatial relationship and degree of separation. This picture thus does not really serve an instructive function. It's just pretty art. Robert K S (talk) 12:02, 7 June 2012 (UTC)
