ImageSc visualises an Eigen::MatrixXd / MatrixXf / MatrixXi as a 2-D image, mapping the data range linearly into a selectable colour map (Jet, Hot, Bone, ...) through ColorMap. It inherits the title / axis-label scaffolding from Graph and is the canvas of choice for sensor-by-sample heat maps, covariance matrices and any other rectangular numeric field that benefits from a glance-able false-colour rendering. Calling ImageSc::updateData repaints the scaled view with new contents.
