The Visual Assessment of (cluster) Tendency (VAT) method readily displays cluster tendency for small data sets as grayscale images, but is too computationally costly for larger data sets. A revised version of VAT is presented here that can efficiently be applied to larger collections of data. A numerical example is included.
