  A method to visualize many-body correlations using the information of the
full wave function is presented. The set of nucleon coordinates which maximizes
the square of the wave function, that is, the most probable spatial
configuration of nucleons, is visualized. The method is applied to Hartree-Fock
(HF) and HF+BCS wave functions of $p$- and $sd$-shell $N=Z$ even-even nuclei to
analyze the many-body correlations in those systems. It is found that there are
$\alpha$-cluster-like four-body correlations already at the HF level in some of
the nuclei. The effects of pairing on the most probable configuration are also
investigated. The method is useful to analyze the nuclear many-body
correlations, and it suggests a new viewpoint to microscopic nuclear wave
functions.
