La bildo estas kopiita de wikipedia:en. La originala priskribo estas:

This image shows a polar graph of the Riemann zeta function along the critical line. That is, it is a graph of \Re\zeta(it+1/2) versus \Im\zeta(it+1/2) for real values of t running from 0 to 34. The first five zeros in the critical strip are clearly visible as the place where the spirals pass through the origin.
