Types of graphsThere are many types of graphs.Learning to read and create graphs is a very useful skill In this unit, you will learn about pictographs, bar graphs,double bar graphs,line graphs, and circle graphs. Let us start with pictographs: A graph is a visual way to display information. A pictograph is a graph that uses pictures or symbols to display information. The pictures in a pictograph usually represent more than one item. The following is a pictograph:  The graph above has a title and a scale. Let say that the circles were drawn by David, Peter, John, Brown, and Jennifer. The title is "number of circles drawn" The scale used is the following: one circle represents 5 circles. David drew 15 circles since we have 3 circles and each circle represents 5 circles. John drew 7.5 circles. How did we get 7.5? Note that if a circle represents 5 circles, half a circle will represent 5/2 circles or 2.5 circles. Add 5 circles to 2.5, give 7.5 Exercise: Construct a pictograph with the following table:  Here is the pictographs:
