A chart is a graphical representation of data, in which «the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart».

A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data. Other domain specific constructs are sometimes called charts, such as the chord chart in music notation or a record chart for album popularity. Charts are often used to ease understanding of large quantities of data and the relationships between parts of the data. Charts can usually be read more quickly than the raw data. A chart can take a large variety of forms, however there are common features that provide the chart with its ability to extract meaning from data. Typically the data in a chart is represented graphically, since humans are generally able to infer meaning from pictures quicker than from text.

Text is generally used only to annotate the data. One of the most important uses of text in a graph is the title. A graph’s title usually appears above the main graphic and provides a succinct description of what the data in the graph refers to. Dimensions in the data are often displayed on axes. If a horizontal and a vertical axis are used, they are usually referred to as the x-axis and y-axis respectively.
