Charts (graphs)

Charts, or graphs, are visual tools used to represent data clearly and efficiently. They transform numbers into images—like bars, lines, or pie slices—making patterns and relationships easier to see and understand. For example, bar charts compare different categories, line graphs show trends over time, and pie charts illustrate parts of a whole. By presenting data visually, charts help people grasp key insights quickly, supporting better decision-making without digging through complex tables. They are widely used in business, science, and everyday life to communicate information effectively.
