Graphs and charts are mostly used for the same graphical purpose, which is to make data easier to understand and interpret. However, there are some fundamental differences between the two.
• A graph is used to represent data in a visual format and is made up of multiple points that have a relationship not necessarily linear.
• A chart is based on a rectangular or square grid system and each point has a linear relationship.
• A graph usually shows the relationship between data points over a period of time.
• A chart usually shows the relationships between multiple sets of data points in order to draw comparisons.
• A graph usually focuses on one type of information or data such as prices over time.
• A chart usually focuses on multiple data points such as demographics, sales and geographic data.
• Graphs tend to be more technical in nature and often used in scientific fields.
• Charts can be used in a wide variety of fields, including business and finance.
In summary, graphs and charts are both used to show data in visual formats, but graphs tend to display one set of data points over time, whereas charts are best suited for displaying multiple data points in order to draw comparisons.
