"""
This method returns a properly positioned label for the passed graph,
styled with the passed parameters.
Parameters
----------
graph : ParametricFunction
The curve of the function plotted.
label : str = "f(x)"
The label for the function's curve.
x_val : Union[float, int]
The x_value with which the label should be aligned.
direction : Union[np.ndarray,list,tuple]=RIGHT
The position, relative to the curve that the label will be at.
e.g LEFT, RIGHT
buff : Union[float, int]
The buffer space between the curve and the label
color : str
The color of the label.
Returns
-------
TexMobject
The LaTeX of the passed 'label' parameter
