A gráfica (graph) is a visual representation of data that helps to illustrate relationships, trends, or patterns. It can take various forms, such as bar graphs, line graphs, or pie charts, each serving a specific purpose in displaying information clearly and effectively. Graphs are commonly used in fields like mathematics, science, and economics to simplify complex data sets. Graphs typically consist of two axes: the horizontal axis (x-axis) and the vertical axis (y-axis). The data points are plotted on these axes, allowing viewers to quickly interpret the information. By using a gráfica, individuals can make informed decisions based on visualized data, enhancing understanding and communication.
