This document presents information on the advantages of diagrammatic presentations compared to narrative presentations. It then provides examples of different types of diagrams - pie charts, bar diagrams, flow charts, and tree diagrams - and what each shows. A pie chart shows the world population distribution by country in 2001. Bar diagrams show India's population growth from 1961-2001. A flow chart maps the stages of a rocket launch. And a tree diagram classifies insects into useful, harmful, and neutral categories. Diagrams allow visualizing and comparing information clearly compared to repetitive words in narratives.

3. ADVANTAGES OF DIGRAMATIC
PRESENTATION
A diagrammatic presentation gives you a very clear
and precise idea of the topic you are studying. In the
narrative presentation you have to use the same words
again and again. You can not at a glance compare and
contrast the figures. But you can easily visualize the
information if it is presented with the help of a table, pie
diagrams , etc. so it is necessary to study various ways
of presenting information.

4. •In 1981 the percentage of rural population was 76.7
% (524 millions ), urban population was 23.3% (159
millions).
•In 1991 the percentage of rural population was 74.3
% (629 millions ), and that of urban population was
25.7 % (218 millions ).
•In 2001 the percentage of rural population was
72.22% (741.7 millions ), and that of urban
population was 27.78% (285 millions ).

10. Flow Chart
Flow chart mainly presents stage by stage operation or
procedure.
Main stages of action, Operation or process are briefly stated.
Flow chart gives you a visual impression of the ordering of the
procedure.
It also helps to simplify complexity of procedure or action ,
operation or process.
Flow chart give you the information in action.
See for example the various stages of launching the rocket.

12. Tree Diagram
Tree diagrams are useful for presenting classification.
They show divisions , subdivisions and hierarchical classification of
the components.
Insects are small creatures having six legs, no backbones and body
divided into three parts.
From mans point of view they may be classified into useful , harmful
and neutral types or categories.
Useful insects, for example, are Bees which give us honey,
silkworms that give us silk: harmful insects for example are locusts
and mosquitoes which destroy our plants and spread diseases like
malaria.
Neutral insects, for example are butterflies, I’ birds and moths
which are beautiful and interesting.
