A graph is a visual representation of data or information that uses lines, bars, or other shapes to show relationships between different elements. They are used to display patterns and relationships, making complex data easier to interpret. Graphs can be used to present a variety of information, such as market trends, stock prices, or census figures. Although graphs can be created by hand, computer programs such as Excel or SPSS make it much easier. To create a graph, one must first decide what kind of graph to use, depending on the type of information being presented. Common types of graphs include bar graphs, pie charts, line graphs, and scatter plots. Each type of graph shows different kinds of relationships. In each one, the data points are plotted on the graph's x and y axes, allowing viewers to identify relationships between them. Graphs help people better understand complex topics and make informed decisions.
