        cell_type: Mesh cell type.
        dtype: Float type for the mesh geometry(``numpy.float32``

        ghost_mode: Ghost mode used in the mesh partitioning.
        partitioner: Function that computes the parallel distribution of
            cells across MPI ranks.
        diagonal:
            Direction of diagonal. See :class:`DiagonalType` for
            available options.
        gdim: Geometric dimension. The square lies in the first 2
            coordinate axes; remaining components are zero.

    Returns:
        A mesh of a square with corners at ``(0, 0)`` and ``(1, 1)``.
