Line Graph

the same type of diagram for both works.
They are a useful device for showing parts or shares of totals.
Scientific notation is useful in economics to compute very large or very small numbers.
Line Graph
they show you the percentage cover/abundance of a specific species along a transect, the X-axis is the distance, and the actual kite shapes represent the amount of that species at that set distance.
Entity-Relationship diagrams are useful for modelling data and the relationships between the data. They can be used when the constraints between data are relatively simple. They do not allow specification of interactions between the data or model how the data changes (there are no processes in Entity-Relationship). Entity-Relationship diagrams are most often used to model databases.

Economics uses lots of models to convey economic theory. The use of graphs helps present this information and the relationships within it. Graphs can also be used to extrapolate and interpolate the information and make estimations of values.
PERT diagrams are useful in communicating information about projects through easy visual charts.
They could be useful while determining the valency of atoms and the structures of chemical bonding in plausible ways.
Relationships
Spread sheets, network diagrams
Sankey diagrams are used to visualize the flow of energy, resources, or materials through a system. They are particularly useful for showing the relative magnitudes of different flows and identifying areas of inefficiency or waste within a system. Sankey diagrams are commonly used in areas such as engineering, economics, and environmental science for analysis and communication of complex data.
9 constellations are useful to man, they are useful in showing directions with reference to Pole star.
