The two notable types of Network Diagram are "undirected" and "directed". Undirected Network
Diagrams only display the connections between entities, while directed Network Diagrams show if the

connections are one-way or two-way through small arrows.

Disadvantage:

Network Diagrams have a limited data capacity and start to become hard to read when there are too

many nodes.

Network Diagrams are often used:

To show the structure of the organization,colleges and tourist place.

Tools to Generate Network Diagram Visualisation:

Datamatic

Zoomcharts

Graph-tool

Cytoscape

Vega

3)Population pyramid:

Population pyramid also known as Age & Sex pyramid.

Population Pyramid displays the distribution of population in all age groups and in both sexes.

The X-axis is used to plot population numbers and the Y-axis lists the age groups.

Population Pyramids are ideal for detecting changes or differences in population patterns. Multiple

Population Pyramids can be used to compare patterns across nations or selected population groups.

The shape of a population pyramid can be used to interpret a population. For example, a pyramid with

a very wide base represent population of that age group is in maximum level and narrow base represent
population of that age group is in minimum level.
