Scatter Plot

http://www.stat.yale.edu/Courses/1997-98/101/scatter.htm
A scatterplot is a graph or map of two variables and how they are associated.  The above map is a positive association between the years of education and the amount of income one has.  It shows that the more years of education the more money one will make.  Scatterplots can show negative association or none whatsoever.  Positive slopes upward, negative slopes downward and random dots everywhere obviously states that one variable has nothing to do with another.
