def apply_transformations(data: dict) -> list:
    """
    Applies a chain of transformations converting nodes in `data` using

    - `apply_from`
    - `apply_eval`
    - `apply_each`
    - `apply_ref`

    Returns the different variants of the `data` after transformations as a list.

    ----------
    data
        The dictionary which should be transformed
    Returns
    -------
    list
        the transformed `data` where each item is a version of the data.
