They often include graphs or diagrams that illustrate trends, comparisons, and progress over time. Common types of performance charts include bar charts, line graphs, and pie charts, which help users quickly grasp complex information. These charts are widely used in various fields, such as business, education, and sports, to track performance metrics. By presenting data in a clear and concise manner, performance charts enable stakeholders to make informed decisions and identify areas for improvement.
