Title: A Comprehensive Guide to Using Sankey Charts for Enhanced Data Visualization Skills
Sankey chart, originally introduced by John Houghton, a statistician and climate science expert, is a visual representation of flow of information, resources, or energy. In other words, it is an effective tool for analyzing complex relationships between different variables. The Sankey chart is composed of multiple flow lines that run across the chart, and this provides an accurate way to represent the interconnection between data points. This article aims to illuminate how to create a sankey chart, and applications of the visual tool.
How to Use Sankey Chart to Visualize Data.
-
Choose Subject Matter: The first step in creating a sankey chart is to know what you are visualizing. Do research on the data that you want to create the pie chart, and make a list of all the variables you want to represent. You can use this list to create an accurate representation.
-
Determine Type of Flow: Identify the type of flow that you want to draw information or data. Choose the right flow direction for the flow to make it easier to understand. For instance, positive flow indicates that resource flows to the source while negative flow indicates resources flowing away from the source.
-
Choose Variables to Analyze: Identify the variables that you want to visualized. For example, water flow, wind flow, etc and then choose what variables you want to depict.
-
Diagram the Flow: Use flow diagrams for each variable you want to show. Include the key in the center. Write the name of the variable and the direction of the flow on the left side of the diagram.
-
Customize The Chart: Customize the chart according to the complexity of the data you want to represent. For beginners, a simpler flow pattern is better since it provides a very clear view of the data. If you are not sure what to do, consider using pre-made sankey charts that are available online to get started.
Sankey Chart Applications.
Sankey charts are widely used in different fields such as finance, medicine, and ecology for various purposes. Use Sankey charts to analyze the flow of information, data, or resources across different fields. Here are some of the advantages of using sankey charts in data visualization:
-
Visualization of Interdependencies: Sankey charts help visualize the interdependencies between different processes, enabling quick identification of the flow patterns and analyzing complex relationships.
-
Interpretability: Sankey charts make data interpretation simpler. This makes it easy to understand the direction and the strength of flows.
-
Representation of Complex Relationships: Sankey charts are very effective in visualizing complex relationships involving multiple variables.
Conclusion.
In summary, sankey charts provide a unique way to visualize interconnectivity between different variables. While the process of creating a sankey chart can seem difficult, the potential benefits it offers make it well-worth the effort. By following the steps outlined above, anyone can create attractive and accurate sankey charts. They can help anyone understand complex data and improve their data visualization skills.
