Sankey charts are a powerful tool for visualizing the flow of resources between different entities, such as project costs or human flows. By creating a sankey chart, you can easily and clearly illustrate the dependency structure of a specific set of resources, helping decision-makers make informed decisions. In this article, we will take you through the creation and application of a sankey chart, giving you a step-by-step guide on how to create one.
Step 1: Choose your data
The first step in creating a sankey chart is to choose your data. This data should be represented in a diagram, which will be helpful for creating your sankey chart. You can choose between the following types of visualizations: flow diagrams, node diagrams, and tree diagrams.
Step 2: Select your layout
Once you have your data, you need to select a layout for your diagram. If you are using a node diagram, you can choose the layout that suits your needs, such as a hierarchical layout or a radial layout. For a sankey chart, you can choose between flow node and flow arrow layouts, which will help you visualize the flow of the resources.
Step 3: Choose your colors
Sankey charts are best when the colors are used effectively. You should choose a color palette that complements the colors of your resources. You can also choose a color scale that enables you to clearly distinguish between different resources.
Step 4: Create your sankey chart
Once you have finished selecting your data and layout, you can start creating your sankey chart. You can use software programs like Microsoft Excel, GraphPad Prism, or R to create your sankey chart. You can create a sankey chart by selecting your nodes and arrows, connecting them, and filling the nodes with color. You should also include labels for your resources, as this will help you understand the flow of the resources.
Step 5: Customization
Sankey charts can be customized to fit your needs. You can add additional nodes or arrows, change the color scale, and rearrange the layout. You can also add a legend to explain the labels and arrow shapes.
Step 6: Interpret the sankey chart
Sankey charts are best when the flow is easy to interpret. You can use your sankey chart to understand the flow between different entities, such as project costs or human flows. You can use the sankey chart to make informed decisions and plan future projects accordingly.
Conclusion
Sankey charts are a powerful tool for visualizing the flow of resources, making it easy to understand the dependency structure of a specific set of resources. With the right layout selection, colors, and customization, sankey charts can be highly effective. By using sankey charts, decision-makers can make informed decisions and plan future projects accordingly.
