class WhyLabsTransactionWriter(WhyLabsWriterBase):
    f"""
    A WhyLogs writer to upload profiles onto the WhyLabs platform as a transaction.

    >**IMPORTANT**: In order to correctly send your profiles over, make sure you have
    the following environment variables set: `[WHYLABS_ORG_ID, WHYLABS_API_KEY, WHYLABS_DEFAULT_DATASET_ID]`. You
    can also follow the authentication instructions for the why.init() method at {INIT_DOCS}.
    It is highly recommended you don't persist credentials in code!

    You shouldn't have to supply these parameters to the writer in practice. You should depend on why.init() to resolve
    the credentials for you. These are here for one-offs and testing convenience.

    Parameters
    ----------
    org_id: str, optional
        Your organization ID on the WhyLabs platform. If not informed, will get the mentioned environment
        variable instead.

    api_key: str, optional
        The API Key to authenticate with WhyLabs. If not informed, will get the mentioned environment
        variable instead.

    dataset_id: str, optional
        The Dataset ID, often referred to as model ID, that will tie the profile to your tracked data.
        If not informed, will get the mentioned environment variable instead.
    Returns
    -------
        None

    Examples
    --------
    An example usage of this method can be represented with the simple code above. Here we
    are assuming the user has already assigned a pandas.DataFrame to the `df` variable.

    ```python
    ```
