Graphing is the portrayal of information through visuals such as dots, lines, curves, or bars on a grid. This mathematical tool is used to illustrate the correlations between variables, visually decode complicated data, and estimate future values. Different types of graphs, such as line graphs, bar graphs, pie charts, and scatter plots, all cater to varying analytical requirements.
