A visual representation of data is a graphical representation of information, such as a chart or diagram. A GRAPH is a type of visual representation of data that uses symbols, such as bars, lines, or points, to represent values in a two-dimensional space. Graphs are often used to represent relationships between different variables, such as the relationship between price and demand. Graphs can also be used to compare different sets of data, such as the comparison of sales figures from different years. Graphs are a useful tool for quickly conveying complex information in an easy-to-understand format.
