Charts are visual tools that help us understand and present data in a clear and organized way. They can take many forms, such as bar charts, line graphs, or pie charts, each serving a different purpose. By using shapes, colors, and labels, charts make it easier to see trends, compare values, and identify patterns in information. For example, a bar chart can show how sales numbers change over time, while a pie chart can illustrate the percentage of different categories in a whole. Overall, charts simplify complex data, making it accessible and engaging for everyone, from students to professionals.
