---------------

.. py:class:: CellGraphDataWSI

   Dataclass for Graph Data representing cells or patches in a WSI.

   This class stores node features, positions, and metadata for graph-based
   representations of whole slide images.

   :param x: Node feature matrix with shape (num_nodes, num_node_features).
   :param positions: Each of the objects defined in x has a physical position
                     in a Cartesian coordinate system, be it detected cells or extracted
                     patches. Shape (num_nodes, 2).
   :param metadata: Metadata about the objects stored here. Can include
                    information about cell types, coordinates, or other annotations.
