A Bar Chart (pronounced: /bɑːr tʃɑːrt/), also known as a bar graph or a bar diagram, is a type of data visualization tool used in statistics and other related fields. The term originates from the English words "bar" and "chart", indicating a graphical representation of data using bars of varying lengths.
