3. A diagram is a two-dimensional geometric symbolic
representation of information according to some
visualization technique. Sometimes, the technique
uses a three-dimensional visualization which is then
projected onto the two-dimensional surface. The word
graph is sometimes used as a synonym for diagram.
Here term diagram in common sense can have two
meanings.
visual information device : Like the term "illustration" the
diagram is used as a collective term standing for the
whole class of technical genres, including graphs,
technical drawings and tables.
specific kind of visual display : This is only the genre, that
show qualitative data with shapes that are connected
by lines, arrows, or other visual links.

4.  a form of visual formatting devices
 a display that do not show quantitative data,
but rather relationships and abstract
information
 with building blocks such as geometrical
shapes connected by lines, arrows, or other
visual link.

5. There are at least the following types of
diagrams:
• Graph-based diagrams: these take a
collection of items and relationships between
them, and express them by giving each item
a 2D position, while the relationships are
expressed as connections between the items
or overlaps between the items; examples of
such techniques:

6. tree diagram network diagram flowchart Venn diagram existential graph

7. •Chart-like diagram techniques, which display a relationship between
two variables that take either discrete or a continuous ranges of values;
examples:
histogram bar chart pie chart function graph scatter plot

8. •Other types of diagrams-train
diagram exploded
view
population density
map
Pioneer
plaque

9. A graphical representation of the sequence
of operations in an information system or
program. Information system flowcharts
show how data flows from source documents
through the computer to final distribution to
users. Program flowcharts show the sequence
of instructions in a single program or
subroutine. Different symbols are used to
draw each type of flowchart.

16. Flowcharts can be modelled from the
perspective of different user groups (such as
managers, system analysts and clerks) and
that there are four general types:
Document flowcharts, showing controls over a
document-flow through a system
Data flowcharts, showing controls over a data
flows in a system
System flowcharts showing controls at a physical
or resource level
Program flowchart, showing the controls in a
program within a system

17. Eight steps that insure complete preparation and
execution of a flowchart are-
 Research the problem
 Decide on the method of solution
 Plan the solution
 Outline the system by drawing the system
flowchart
 Check the system flowchart
 Draw a detailed program flowchart for each
program
 Check the program flowchart
 Test the program flowchart and system flowchart
by using data that has been prepared

18.  The flow of the flowchart should be from top
to bottom and from right to left
 Use meaningful descriptions in the symbols
 If the flowchart is complex ,connectors
should be used to reduce the number of flow
lines. Avoid intersecting flow lines.
