Chart symbols are graphical representations used in various types of charts to convey information clearly and efficiently. These symbols can represent data points, trends, or categories, making it easier for viewers to understand complex information at a glance. Common chart symbols include lines, bars, dots, and arrows, each serving a specific purpose in visualizing data. In the context of graphs, maps, or diagrams, chart symbols help to simplify the presentation of data. For example, in a line chart, a line symbol indicates the relationship between two variables over time, while in a bar chart, rectangular bars represent different categories or values. Understanding these symbols is essential for interpreting data accurately.
