Introduction: Sankey charts are a type of flowchart that can depict complex data flow in a visually engaging and intuitive way. They are particularly useful for exploring complex data sets that can be difficult to visualize otherwise. This article will explore the power of Sankey charts, how they can be created and applied, and provide some tips for effective data visualization using Sankey charts.
What are Sankey Charts?
Sankey charts are a type of flowchart that can depict complex data flow in a visually engaging and intuitive way. They work by connecting nodes with data to form a chain of nodes and links that represent the flow of data. Each data node is connected to a data path that specifies the direction and amount of the data flow. The flowchart can be colored to represent the direction of the data, and nodes can be sized to represent the volume of data.
Sankey charts can be used to visualize a wide range of data sets, including financial flows, physical flows, and more complex data sets that involve non-linear relationships. They can be used to show how different data sets impact each other, how data flows between different parts of a system, or how data is distributed across different locations.
Creating Sankey Charts
Creating Sankey charts is relatively simple. You can use specialized software or online tools to create the charts, or you can create them manually using spreadsheets or free vector graphics software. Here are the basic steps for creating a Sankey chart:
-
Identify the data you want to visualize. This data can come from a variety of sources, including financial data, process data, or process flow data. Make sure the data you want to visualize is clear and well-defined.
-
Choose a software tool or online tool to create the Sankey chart. There are several tools available for creating Sankey charts, including Infogram, Lucidchart, and Doodad. Some of these tools have built-in Sankey chart features, while others require customization.
-
Choose a data visualization format for the Sankey chart. The data visualization format will affect the size and style of the Sankey chart. Common formats include arrowheads, nodes with labels, and nodes with color and size.
-
Draw the data in the Sankey chart. Select nodes with data and connect them to each other using links. Each link should specify the direction and amount of data flow. Use arrows or lines to indicate direction, and size the nodes to show volume of data.
-
Customize the Sankey chart as needed. You can adjust the placement of the nodes, adjust the color and size of the nodes, and add labels or annotations to the chart.
Applications of Sankey Charts
Sankey charts can be used to visualize a wide range of data sets, including financial flows, process flow data, and more. Here are some examples of how Sankey charts can be applied:
-
Visualizing Financial Flows: Sankey charts can be used to visualize how different financial streams flow into and out of a company. This can help managers understand the sources of revenue and costs, and make informed decisions that affect the financial health of the company.
-
Visualizing Process Flow Data: Sankey charts can be used to visualize the flow of data through a process. This can help managers identify bottlenecks, optimize processes, and make data-driven decisions that affect the success of the process.
-
Visualizing Non-Linear Relationships: Sankey charts can be used to show how different variables impact each other. This can be useful for understanding complex data sets that involve non-linear relationships, such as those involving the impact of customer purchasing behavior on the supply chain.
Tips for Effective Data Visualization
Effective data visualization using Sankey charts can significantly improve visual communication of complex data sets. Here are some tips for creating impactful Sankey charts:
-
Choose the right data visualization format: The format of the Sankey chart will affect how effective it is. Make sure the format you choose is appropriate for the data you want to visualize.
-
Customization: Customization is key when it comes to creating effective Sankey charts. This can involve adjusting the placement and style of the nodes, adding labels or annotations, and adjusting the color and size of the nodes.
-
Pay attention to the flow direction: Paying attention to the flow direction is crucial for understanding the flow of data. If possible, have the flow directions clearly specified, so users can easily understand the implications of their decisions.
In conclusion, Sankey charts are a powerful tool for visualizing and communicating complex data set. They are easy to create and can be used to explore a wide range of data sets, from financial and process data to more complex data sets involving non-linear relationships. With the right data visualization format and customization, Sankey charts can help you better understand and communicate complex data sets effectively.
