 class FuzzySet:
-    """
-    A class for representing and manipulating triangular fuzzy sets.
-    Attributes:
-        name: The name or label of the fuzzy set.
-        left_boundary: The left boundary of the fuzzy set.
-        peak: The peak (central) value of the fuzzy set.
-        right_boundary: The right boundary of the fuzzy set.
-    Methods:
-        membership(x): Calculate the membership value of an input 'x' in the fuzzy set.
-        union(other): Calculate the union of this fuzzy set with another fuzzy set.
-        intersection(other): Calculate the intersection of this fuzzy set with another.
-        complement(): Calculate the complement (negation) of this fuzzy set.
-        plot(): Plot the membership function of the fuzzy set.
