A graph refers to a diagram or image used to represent information, especially numerical data through lines, bars, among others depending on the type of graph. In the case of pie charts, these graphs include a circle that represents the100% of some variables, for example, students in a school, and that is divided into portions to represent specific data, for example, students that like volleyball, soccer, baseball, etc. This graph differs from others because most graphics include two axes, but pie charts only include a circle and portions on it representing data.
