Sankey diagrams are a type of flowchart that helps in visualizing complex data in a simplified manner using arrows pointing to areas for detailed analysis and investigation. They are widely used in various industries, especially in healthcare, finance, engineering, and public administration to visualize different types of data, from revenue and profit flows to customer interaction flows and more.
What is a Sankey Chart?
A Sankey diagram is a type of flowchart that is used to visualize complex data. These diagrams are called Sankey Diagrams after Samuel Sankey, an Irish physician and statistician who developed the diagrams in the 19th century to visualize the flow of disease through a society.
Sankey charts have an attribute that makes them easier to understand than other flowcharts – they show the direction of flow of a set of variables (such as money, income, investments, or customers) between separate sources and destinations. The arrows connect the source to the destination, with each arrow representing a variable flowing from one source into another.
How are Sankey diagrams used to Visualize Complex Data?
Sankey diagrams are particularly useful in visualizing complex data in a way that is easy for the user to understand. They can be used to visualize different types of data, such as revenue and profit flows, customer interaction flows, or the flow of money from different sources and destinations.
For example, in healthcare, a sankey chart can be used to visualize the different paths a patient goes through in their treatment, showing how medications and treatments flow through the healthcare system. In finance, a sankey chart can be used to visualize the different paths that money flows through a company, showing how it moves from the balance sheet, through profit and loss, and out the exit path.
Sankey charts come in a variety of shapes and sizes, and can be used in conjunction with other visualization tools and software to achieve the best possible results.
What are the benefits of using Sankey diagrams for data visualization?
Sankey diagrams are particularly beneficial for businesses and organizations because they help to provide clarity on complex data, especially in areas where there may be a lack of understanding or confusion. They are also useful for exploring different variables and paths of data flow.
One of the key benefits of Sankey charts is that they are visual in nature, making it easier for users to understand the data and see the different paths that different variables take. This can help to identify bottlenecks and areas for improvement in different departments or areas of the business.
Sankey Charts also simplify data analysis by showing the flow between different variables, making it easier to focus on the parts of the problem that matter most.
In conclusion, Sankey diagrams are a powerful tool for data visualization, providing a clear and concise way to visualize complex data in a simplified manner. Their use for data analysis in different industries makes them a versatile and effective visualization tool, helping to reveal new insights about the data and driving decision-making.
