A Ford circle is a geometric construct that is used in number theory to visually represent the fractions between 0 and 1. Specifically, for each positive fraction \\( \\frac\{p\}\{q\} \\) (where \\( p \\) and \\( q \\) are coprime integers), the corresponding Ford circle is centered at \\( \\frac\{p\}\{q\} \\) with a radius of \\( \\frac\{1\}\{2q^2\} \\).
