A pictograph represents data through pictures of different kinds of objects.  This is an example of a pictograph.

This pictograph shows the number of students travelling through bus, car, cycle and on foot.

A bar graph is a graphical representation of data where the numerical values are represented by the height of the graph with the same equal width of all the different bars. Take this for example, a bar graph representing marks obtained by students in different subjects.
