Charts and graphs are visual tools used to represent data and information clearly and concisely. They help people understand complex information at a glance by displaying relationships, trends, and comparisons. Common types include bar charts, line graphs, and pie charts, each serving different purposes depending on the data being presented. These visual aids are widely used in various fields, including business, education, and science. By transforming numerical data into visual formats, charts and graphs make it easier for audiences to interpret information, identify patterns, and make informed decisions based on the presented data.
