     Parameters
     ----------
-    name : string (optional)
+    name : str (optional)
         The name of the parameter. If not specified, a unique name will be
         created.
-    value : any (optional)
+    value : Any (optional)
         The default value of the parameter. If not specified, the parameter
         will be created without a default value.
     bind : :class:`Binding`, str (optional)
         Binds the parameter to an external input element such as a slider,
         selection list or radio button group.
-    empty : boolean (optional)
+    empty : bool (optional)
         For selection parameters, the predicate of empty selections returns
         True by default. Override this behavior, by setting this property
         'empty=False'.
     expr : :class:`Expr` (optional)
         An expression for the value of the parameter. This expression may
         include other parameters, in which case the parameter will
         automatically update in response to upstream parameter changes.
-    encodings : List[str] (optional)
+    encodings : Sequence[str] (optional)
         A list of encoding channels. The corresponding data field values
         must match for a data tuple to fall within the selection.
-    fields : List[str] (optional)
+    fields : Sequence[str] (optional)
         A list of field names whose values must match for a data tuple to
         fall within the selection.
-    on : string (optional)
+    on : str (optional)
         A Vega event stream (object or selector) that triggers the selection.
         For interval selections, the event stream must specify a start and end.
-    clear : string or boolean (optional)
+    clear : str, bool (optional)
         Clears the selection, emptying it of all values. This property can
         be an Event Stream or False to disable clear.  Default is 'dblclick'.
-    resolve : enum('global', 'union', 'intersect') (optional)
+    resolve : Literal['global', 'union', 'intersect'] (optional)
         With layered and multi-view displays, a strategy that determines
         how selections' data queries are resolved when applied in a filter
         transform, conditional encoding rule, or scale domain.

         point selections.

         When true, an invisible voronoi diagram is computed to accelerate
         discrete selection. The data value nearest the mouse cursor is
         added to the selection.  The default is False, which means that
