A chart is a graphical representation of data that allows users to see the results of data to better understand and predict current and future data. Charts are visual expressions of data and can be used in a number of different fields and real-world applications. They are frequently used in business settings and can help viewers quickly grasp the information being conveyed. Charts can represent tabular numeric data, functions, or some kinds of quality structure and provide different information. There are a wide variety of charts available to display data, including area charts, bar charts, column charts, flow charts, Gantt charts, graphs, line charts, pie charts, and point charts. Charts can make data interesting, attractive, and easy to read and evaluate, and they can also help you to analyze and compare data. In Microsoft Excel and other spreadsheet programs, there are two types of charts: an embedded chart and chart sheet.

Some key components of a chart include:

• Plot area: The area where the chart is plotted.
• Data points: The data series that are plotted in the chart.
• Horizontal (category) and vertical (value) axis: The axis along which the data is plotted in the chart.
• Legend: The charts legend.
• Chart and axis title: A chart and axis title that you can use in the chart.
• Data label: A data label that you can use to identify the details of a data point in a data series.

Charts can usually be read more quickly than the raw data and are used in a wide variety of fields. They can be created by hand or by computer using a charting application. By visually showing the relationship(s) between sets of data, a chart can help bring information to light in an easier-to-comprehend manner than reading blocks of text. This is a much better approach than showing lists or tables of numbers that force viewers to process the information and determine trends.
