Bar Chart

A bar chart is a graphical representation of data using rectangular bars, where the length of each bar is proportional to the value it represents. Bar charts are commonly used in finance, statistics, and various fields to compare different categories or track changes over time. The bars can be displayed vertically or horizontally. In finance, bar charts are often used to show the performance of stocks, sales figures, or other financial metrics, making it easy to see trends and patterns at a glance. They are particularly useful for comparing data across different groups or for tracking the progress of a single variable over time.

Example

A bar chart might be used to compare the quarterly sales of a company across different years, with each bar representing sales for one quarter.
