visualization of posterior distribution for a matrix? Via Bayesian analysis, I generate the posterior samples for a 2D matrix, representing a correlation matrix for instance. Is there any way or tool to visualize these two dimensional random samples?

A two-dimensional correlation matrix could be visualized via an ellipse in the plane, see for instance

But that is one correlation matrix, and you ask for a sample. You could try overplotting them (maybe using transparency), or clustering them and plotting representatives.
