             Line Graph
 A type of graph that highlights trends by
  drawing connecting lines between data
  points.
 Typically used when showing changes over
  a period of time.
               Bar Graph
 Display numerical data by rectangular bars.
 The bars can run vertically or horizontally.
 The length of the bars indicates the quantity
  being represented.
               Pie Graph
 Used to represent a whole
 The pie-shaped sectors represent the parts in
  proportion to the whole.
 The parts of the pie need to add up to 360
  degrees because it is a whole circle.
      Stem-and-Leaf Graph
 A quick numerical method of providing
  visual summary of data.
 Great to show clusters and gaps in the data.
 Called the stem-and-leaf graph because the
  graph resembles a stem and its leaves.
              Pictographs
 Similar to bar graphs.
 Individual icons or figures are used to
  represent the data.
 The icons or figures represent the same
  value.
