The given pictograph expresses the following information:

- The kinds of conveyance used by the students.
- The number of students using conveyances and the number of students coming and going on foot.
- The number of students using school-bus, own car, bicycle, rickshaw, taxi, etc.
- Percentage of students using hired tempo or rickshaw, own car or scooter, cycle etc., fraction of students coming and going without any vehicle.
- Percentage of students related to rich family. Students having their own cars belong to rich families.

- First of all, the related data is collected. For example, to form the pictograph showing the number of boys and girls in different classes and in the school as a whole, the number of boys and girls in different classes are counted. As, I (35B, 20G), II (30B, 10G), III (10B, 30G), IV (25B, 35G), V (20B, 20G) [B for boys, G for girls]

- Different symbols are selected for different types of data. As, for the symbol of a boy and a girl, we select a boy’s face and a face with long hair for a girl.

- A framework containing columns and rows is made according to necessity.

- The related symbols are made at proper places. The symbol must be clear, simple and recognizable. They should be self-explanatory.
