A graph and chart are two types of visual representations of data. A graph typically consists of a series of points, lines, bars, areas, or other visual elements that represent the data within. Graphs can be used to compare, visualize, and interpret complex data. Charts, on the other hand, are typically used to compare large amounts of data in an organized and easy to understand way. Charts are often used to present information in a way that can be easily interpreted or understood. Both graph and chart types provide powerful ways to present data in a visual form.
