Give an example of a visual representation/piece of visual art that is related to relationship and explain the significance.Relationships can be...

This will be as wide open a set of answers that you will
get because the topic and the medium are both fairly large canvasses for answers.  I
will move off the beaten path a bit and suggest Berthe Morisot's work, "On the Balcony"
as an example of Impressionist Art that captures a moment and expands it in the mind's
eye.  The backdrop is a woman and child, presumably mother and daughter, standing on an
overpass.  The child is standing to peer over or through the guardrails, while the
mother is next to her.  I think that this art sample really catches much about the
style, the content, and the emotions present between mother and child.  On one hand, I
think that one can look at the mother and daughter, enjoying a moment in the middle of a
cosmopolitan setting.  Another examination could show that there is a look of protection
and devotion the mother renders to the child.  While the latter is looking out at the
world, the former is looking at her world, the child.  Along these lines, another look
could show a potential disengagement between the mother and her life.  Perhaps, her
looking at her daughter is one agonizing moment where disenchantment with consciousness
is revealed.  There is much within this portrait showing emotional complexity and
technical mastery.
