Circle graphA circle graph is a circle with n equidistant points. (In graph theory, the proper term would be "vertex.") It represents the remainder of x divided by n (called the modulus of integer division). It is useful in number theory for finding interesting properties of series. It is also useful for teaching children about repeating end digits in multiplication: a circle graph with 10 vertices, with the multiples of three graphed in sequence, results in [0,3,6,9,2,5,8,1,4,7,0], with the sequence infinitely repeating.
