   2. a diagram symbolizing a system of interrelations of
      variable quantities using points represented by spots, or
      by lines to represent the relations of continuous
      variables. more than one set of interrelations may be
      presented on one graph, in which case the spots or lines
      are typically distinguishable from each other, as by
      color, shape, thickness, continuity, etc. a diagram in
      which relationships between variables are represented by
      other visual means is sometimes called a graph, as in a
      bar graph, but may also be called a chart.
