Graphs can be used in real life in many ways. For example a line graph in the form of a straight line signifies a linear relationship between two quantities represented on x-axis and y axis. That would show, whether one of them increases and the other decreases, or, both of them increase or decrease simultaneously and also whether one of them increase more than the other.

Then there are bar graphs, circle graphs which show comparative magnitude of different items at a glance. For example a bar graph may depict relative strength of various communities comprising a town population. A circle graph may show the percentage expenditure incurred on different household items during a month .
