What is the use of graphs?

The graph can be defined as a pictorial representation or a diagram that describes data or values in an organized manner. A graph demonstrates the data easily in an understandable manner.

Uses of graph

Graphs and charts are very useful because they are used for communicating information in visual form. These are used in all fields like in newspapers, businesses, magazines, to show the economic data, annual reports, profits and loss, even used in maths and all other branches of science like chemistry and Physics to show the variations and relation between two variables.

  • The graph is easily understood by everyone without any prior knowledge.
  • Graph saves time
  • The graph enables us to relate and compare the data for different time periods
  • The graph is used in statistics to determine the mean, median and mode for different data, as well as in the interpolation and the extrapolation of data.

When some complicated information is appeared to problematic and requires a design then a graph is the most suitable idea to represent them. It shows all features quickly and visually.

In Maths

In maths, graph plays a major role in representing large data and numerical.  This is a source that is used in coordinate system of maths and easily reflects a function and also useful for calculations based on the functions. This is a representation of objects which are a link to one another. These objects are shown on two vertices one is x and the other is the y-axis.

In Physics

In explaining the motion graphs that are used to represent the motion of object. It can be of various types like the graph between distance and time which shows the variation in the distance with time, speed and time graph, the graph for projectile motion or Simple Harmonic Motion etc.

In Chemistry

In chemistry, graphs are used to plot between the temperature, volume and concentration that helps us to know exactly at what point is the solution being diluted or concentrated. We can also plot many other parameters using this graph.
