+    Parameters
+    ----------
+    probs : Dict[str, np.ndarray]
+        Dictionary mapping a label or group name to an array of predicted
+        probabilities for the positive class.
+    reals : Union[np.ndarray, Dict[str, np.ndarray]]
+        Ground-truth binary labels (0/1) as a single array, or a dictionary
+        mapping the same label/group keys used in ``probs`` to arrays of
+        ground-truth labels.
+    decision_type : str, optional
+        Either ``"conventional"`` (decision curve) or another value that
+        implies the "interventions avoided" variant. Default is
+        ``"conventional"``.
+    min_p_threshold : float, optional
+        Minimum probability threshold to include in the curve. Default is 0.
+    max_p_threshold : float, optional
+        Maximum probability threshold to include in the curve. Default is 1.
+    by : float, optional
+        Resolution for probability thresholds when computing the curve
+        (step size). Default is 0.01.
+    stratified_by : Sequence[str], optional
+        Sequence of column names to stratify the performance data by.
+        Default is ["probability_threshold"].
+    size : int, optional
+        Plot size in pixels (width and height). Default is 600.
+    color_values : List[str], optional
+        List of color hex strings to use for the plotted lines. If not
+        provided, a default palette is used.

+    (like ``min_p_threshold`` and ``max_p_threshold``) are forwarded to
