This image shows the path of the Riemann zeta function along the critical line. That is, it is a graph of ${\displaystyle \Re \zeta (it+1/2)}$ versus ${\displaystyle \Im \zeta (it+1/2)}$ 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.
