Venn diagram
noun
(set
theory)
A
diagram
representing
some
sets
by
contours
of
closed
shapes,
such
as
circles
or
ellipses
(and
sometimes
also
the
universal
set
as
a
rectangle
enclosing
all
of
these
shapes),
and
indicating
the
relationships
between
the
sets:
by
overlapping
the
shapes
to
show
that
the
corresponding
sets
have
a
non-empty
intersection,
and
by
possibly
(but
not
necessarily)
enclosing
all
of
the
sets
(which
are
proper
subsets
of
the
universal
set)
within
a
universal
set
(represented
typically
by
a
rectangle);
such
that
the
total
number
of
simply
connected
regions
is
2ⁿ,
where
n
is
the
number
of
depicted
sets
which
are
proper
