- "As we have seen Dimensioned containers make it easy to explore multi-dimensional datasets by mapping the dimensions onto visual layers (`NdOverlay`), 2D grid axes (`GridSpace`), widgets (`HoloMap`) or an arbitrary layout (`NdLayout`). In the [next section](06-Dimensioned_Containers.ipynb) we will discover how to construct composite objects of heterogeneous data."
