%description
Provides a 'ggplot2' extension for drawing Hinton diagrams, a
visualisation technique for numerical matrices in which the area of each
square is proportional to the magnitude of the corresponding entry. For
signed data, white squares indicate positive values and black squares
indicate negative values on a grey background. Hinton diagrams are
especially useful for visualising PCA weight matrices, correlation
matrices, and transition matrices.
